Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2011.Cataloged from PDF version of thesis.
Includes bibliographical references (p. 28-30).
The aim of this paper is to perform a review of Biomimicry as a science today in environmental, engineering, and manufacturing fields, as well as to educate readers on the history of Biomimicry as a whole and how it is studied. As more evidence surfaces about the effect of our presence on the Earth, the scientific community is faced with the challenge of solving these problems. After introducing these concepts, an in-depth review of two of the most studied topics in biomimicry is conducted: how the lotus remains clean in a dirty swamp and how the gecko can stick to any surface. These two topics are taken from the classical beliefs on how they work and leads them through into today's world, focusing on how the mechanisms behind them were discovered. Both sections end with a review of current applications of the technologies that have been developed by studying these living organisms. Everything is wrapped up with a discussion of why we must continue to study biomimicry and apply its principles to our engineering and production practices.

Vi behöver minska vår materialkonsumtion, idag gör vi av med mer resurser än vad vi har tillgång till. I den här studien har först en materialkonstruktion tagits fram och därefter ett produktkoncept för konstruktionen. För att ta fram materialkonstruktionen har biomimicry använts. Biomimicry är designmetoder för att lösa designproblem med inspiration från naturen. Naturen använder sig av så lite material som möjligt. Materialkonstruktionen är inspirerad av växtceller. Konstruktionen har två hierarkier som går i två olika riktningar, en riktning som går längs med och en riktning som går i djupled.För att hitta ett produktkoncept för materialkonstruktionen har material driven design (MDD) använts. MDD är en experimentell metod för att lära känna ett material och förstå dess användningsområde. Produktkonceptet är en stapelbar pall.För att minska på resurser används 3d-printning. 3d-printning är en additiv teknik och minskar på så sätt materialåtgång. Dessutom kan allt material lätt återanvändas eftersom det bara behövs ett material.Produkten kan produceras lokalt vilket minskar på transporter. PLA har använts som material i den här studien.We need to reduce our material consumption, today we are wasting more resources than we have access to. In this study, a material construction was first developed and then a product concept for the construction. Biomimicry has been used to develop the material construction. Biomimicry are design methods for solving design problems with inspiration from nature. Nature uses as little material as possible. The material construction is inspired by plant cells. The construction has two hierarchies that go in two different directions.To find a product concept for the construction, material driven design (MDD) has been used. MDD is an experimental method used to get to know a material and understand its application. The product concept is a stackable pallet.To reduce resources, 3D printing is used. 3D printing is an additive technology and thus reduces material consumption. In addition, all material can be easily reused as only one material is needed.The product can be produced locally, which reduces on transport. PLA has been used as material in this study.

Full textAbstract:
Spider silk is known for its extraordinary material properties, being both very strong and extensible. Even though the fibers outperform many synthetic and natural materials, it is impractical to collect industrial amounts of silk from spiders due to their cannibalistic and venomous nature; they cannot be farmed like the commercial silk worm Bombyx mori. Thus, scientists have turned to molecular and engineering techniques to replicate the spider's silk and spinning apparatus. In the current literature there is no detailed protocol on the production of consistent synthetic fibers. To accomplish this, the fibroins and natural spinning apparatus were taken apart and analyzed in order to develop a protocol that biomimics the spider's system. The laboratory procedure, using the natural process as an example, was simplified to: protein production, purification, concentration, fiber spinning, and lastly post spin draw. Large quantities of truncated MaSp I spidroin (spider fibroin) was purified from E. coli and successfully spun into fibers using customized spinning, spooling, and stretching apparatuses. The final fiber products displayed mechanical properties that were comparable to other reported synthetic fibers, but more importantly also displayed low experimental variability between samples. The protocol developed in this study can be further used to characterize other spidroins and silk proteins, and can be further advanced to produce even better fibers with enhanced properties.

Full textAbstract:
The goal of this thesis is to understand how the Biomimicry Toolbox (BT), a practical tool for applying biomimicry, currently supports strategic thinking in order to create sustainable solutions. A pragmatic qualitative research approach was used, in which the BT was analysed through the lens of the Five Level Framework (5LF), a tool for planning and analysing in complex systems and the Framework for Strategic Sustainable Development, the application of the 5LF for sustainability endeavours. Interviews were conducted with people experienced with the BT. Results show that the BT has several aspects of strategic thinking. It supports the application of a systems perspective, provides a success goal to move towards and offers tools for a strategic process to follow. The authors conclude that the BT could benefit from including understanding of the patterns and structures of the social system in relation with the earth system. Also, it can benefit from including a section on upstream thinking helping users of the BT consider root causes. Lastly, it could benefit from a strategic approach for evaluating how sustainable solutions are and include a simple and clear prioritisation process. The improvements can make the BT more impactful in supporting societies transition towards sustainability.

The aim of this thesis is to develop a new process of product design, also an introduction to the example of an industrial sector in the context of new product development concept. In this thesis, the concept of new product development is examined and the different stages of the process of the tensile machine, testing base frame development are analyzed considering its objectives, implemented procedures, functions and responsibilities division. New product development approach is necessary for the creation of products that assure the need of industrial customers and differentiate the company from the competition. The traditional product development approach based on concept development, validation, and manufacturing phases, has been outdone and the present most used and successful approach is the one that integrates stages and functions. The aim of this paper is to present the process of a new product, an introduction to the example of a base frame tensile machine in the context of new product development (NPD) concept.

Full textAbstract:
The classes of materials used in the biomedical field are manifold: metals, ceramics, polymers and their composites. All these materials are often used in synergic combination in order to meet different requirements. In the design of a biomedical device and in the selection of the materials it is made of, the requirements are particularly stringent since, in addition to carry out its primary function, the device itself must not hamper the host body.
Therefore, biomaterials must, first and foremost, ensure biocompatibility.
Aiming at the synergic integration of implanted biomaterials with the host organism, a design framework results crucial: biomimicry. It is straightforward to get inspiration from structures and solutions occurring in Nature in order to design devices intended to operate in symbiosis with a living organism.
The work presented in this thesis was conceived and developed within such outlook. Two major topics were addressed: ElectroActive Polymers (EAPs), used as artificial muscles and Magnesium foams, used as orthopaedic implants.
As far as EAPs are concerned, it was studied their implementation in actuation devices manufactured according to bioinspired geometries, which can reproduce as faithfully as possible the structure of natural muscle tissues. In fact, in line with the principles of biomimicry, the structures proposed recall the human physiology of muscle bundles, and allow the integration of a recruitment mechanism of the motor units.
EAPs have a typical transducers behaviour: if prompted with an electric signal (in particular a voltage), they react with a mechanical deformation, and vice versa. Therefore, EAPs can be described as smart materials, suitable to be used both as actuators and as sensors. As actuators, EAPs have several advantages over the solutions currently present in the state of the art of traditional robotics. In fact, EAPs allow more fluid and biomimetic movements, if compared to those achievable with mechanical counterparts: polymers are flexible and not limited by the rigidity of devices relying on gears and bearings. For this reason, and thanks to stress and deformation values similar to those of biological tissues, EAPs are also referred to as “artificial muscles” [1].
As far as magnesium foams are concerned, within a biomimicry outlook, the context of orthopedic surgery sets the morphology of natural bone as reference. Designing choices regarding materials selection, production methods and treatments (in bulk and/or on surface) were addressed to reproduce the mechanical and functional features of natural bone. In fact, if on one side the orthopaedic implant is required not to collapse under the mechanical load applied, on the other it should not bear excessively or exclusively the forces acting on the bone in order not to induce a stress-shielding effect. This phenomenon, in fact, may be critical since it reduces considerably the stimulation of regenerative bone cells and, ultimately, slows down the recovery of natural bone. The natural bone has a complex structure, resulting from millions of years of evolution, which fulfils several functions: it provides specific structural support, locally adapted to load conditions; it does not add unnecessary weight by means of an optimized minimization of mass and it allows nutrients supply to tissues through adequate vascularization. Such multi-functionality is enabled by the peculiar structure of the spongy bone tissue. Starting from these observations, the mimesis of cancellous bone conformation is one of the most appropriate guideline in choosing and designing materials for orthopaedic applications.
Among the feasible technological solutions, metallic foams with open interconnected porosity have been identified as the most promising choice [2]-[5] and this thesis is focused on this solution. In fact, these materials can be designed to combine the mechanical properties and the morphological characteristics of natural bone, as well as the vascularization function and the stimulation of bone tissue growth. Furthermore, metallic foams represent one of the most suitable option to coherently develop a biomimetic device that reproduces the main features of natural bone.
In the light of the requirements outlined so far, pure magnesium represents an optimal solution. This metallic material in fact meets the multi-functionality requirement previously described: it has mechanical properties of the same order of magnitude as those of natural bone tissue, it can be produced in the form of foam, it is biocompatible and bioresorbable. This last feature enables the possibility to avoid second surgery usually needed to remove orthopedic devices once their function is fulfilled. Supporting this choice, there is a wide scientific literature which, in recent years, has recognized magnesium as a very promising material for biomedical applications, although there are still some critical aspects to be solved. In fact, the process of corrosion of magnesium in the body fluids results in the formation of gaseous hydrogen that, if produced too rapidly, can be harmful for the human body [4].

Increased environmental consciousness in recent years, stimulated by concerns about human induced climate change, has motivated a desire to reduce the impact of the built environment through eco efficient design imperatives. This evolution has provided eco practitioners with multifaceted challenges in making their practices more ecologically sustainable through optimal approaches to design. One such design approach to ecological sustainability is to emulate or take creative inspiration from natural systems, often referred to as biomimicry. This study examines how eco practitioners perceive biomimicry as a design approach in architectural eco design practice. An exploratory approach, taking a post-positivist epistemological framework informed a mixed method, correlational, project-based research design. The theoretical contribution was a model and framework for biomimicry thinking which suggested ways of addressing problems of conceptualisation and understanding the complexities of ecological integration that had been identified as barriers to the practice of ecologically sustainable design. The empirical contribution was a recommendation for a Biomimicry Approach, which proposed a simultaneous use of indirectly mimicking and directly mimicking to architectural eco design projects. Multivariate statistical analysis recognised biomimicry principles, design propositions and physical attributes as the most significant predictors that can enhance ecological sustainability in architecture. The study’s outcome in relation to biomimicry advanced understanding of ways to reduce waste by efficient spatial design was seen as a contribution architects can make to the concept of a reduction scenario for the ecological age. This thesis adds important knowledge to underpin future research and recommends biomimicry design indicators, biomimicry design matrix and possibilities for the use of vernacular architectural strategies for the development of architectural eco design practice.

Full textAbstract:
The notion of sustainability has become an extensive area of research ever since the term emerged in the late 1980s, due to the negative effects of unsustainable production and consumption patterns on environmental stewardship, social equity and economic development. There have been various approaches developed for product design and education within the context sustainability. Biomimicry is one of those approaches, and its implications for product design education have recently started to be explored. In this study, an educational tool - Biomimicry Sketch Analysis (BSA) - was developed and integrated into the idea-generation phase of an educational design project at the undergraduate level in the Department of Industrial Design at the Middle East Technical University (METU). This integration is analyzed throughout the graduate thesis study, to understand and explore the implications of the biomimicry approach for sustainability in product design education. The educational tool within this approach was found as influential among the third year industrial design students for the idea-generation phase, yet the results of this study included both pros and cons for the incorporation of the BSA exercise.

Full textAbstract:
This thesis explores strategies to improve some facets of biocompatibility deficiencies of synthetic vascular grafts using a biomimicry approach by adding PF8, a fibrillin-1 recombinant fragment. PF8 contains RGD, a potent amino acid sequence that strongly binds to endothelial cells (ECs), smooth muscle cells (SMCs) and fibroblasts. Our In vitro assessments showed remarkable EC attachment and proliferation on PF8. PF8 was covalently bound to PTFE after surface activation with plasma immersion ion implantation (PIII) technology. Preserved PF8 favourable interactions with ECs after immobilisation on PTFE was confirmed. PF8 coating also decreased thrombus formation on PIII treated PTFE. We also demonstrated a method to decrease thrombogenicity of PTFE by covering the surface of PIII PTFE with autologous serum. Finally, we explored the possibility of making a biofunctionalised biodegradable graft. We made an electrospun polycaprolactone (PCL) graft with a 2mm diameter with favourable structure and mechanical properties. The PCL graft was biofunctionalised with PF8 binding using PIII technology. PF8 coated PCL and control PCL grafts were implanted as abdominal aorta interposition grafts in a rat model for 3 and 6 weeks (n=4 for each group, total n=16). No aneurysmal degeneration was noted and there was a layer of luminal EC in all grafts. The patency was significantly lower in the control group. After 3 weeks, there was a trend towards decreased intimal hyperplasia in PF8 coated PCL grafts. After 6 weeks, there was a significant reduction in lumen loss in PF8 coated PCL graft compared to the controls. This finding denotes antiproliferative effect of PF8 on SMCs for the first time in vivo. Remarkable affinity to enhance EC cell attachment and proliferation and suppressive effect on intimal hyperplasia combined with its non-thrombotic nature, make PF8 an excellent candidate to improve biocompatibility of new tissue-engineered vascular grafts.

Full textAbstract:
The global economic operating system of capitalism is incongruent with the values required to sustain life on a planet with a growing population and finite resources. Living in marginalized communities the impoverished are the most negatively affected by the current system, as they are the most vulnerable to the vicissitudes of climate change, resource extraction, labor exploitation and wealth concentration. Our way of life needs to be reimagined to align with principles that are in accordance with the ecological worldview. Aspects of an effective strategy rooted in the ecological worldview - especially Biomimicry, Biophilia and a Living Labs approach - are being created in silos but lack application at a systems level. The objective of this research is to bridge the disparate streams of these concepts into a community-based model, with the aim of replicating the emergent system in order to build alternatives to the current model. The research question to explored is the following: how can the principles of Biomimicry, Biophilia, and Living Labs be integrated and systemically applied in communities? Investigating this question will bring forth the Principles for Transition Infrastructure - an approach to building a resilient, self-sustaining, regenerative model for an alternative way of living. This research concludes that there is an opportunity to dismantle the mechanistic worldview of isolating problems in silos and rather observe the multiple points of interconnectivity that weave together a solution that transcends the parts of the whole. In doing this, we draw from multiple disciplines and find the synergies to construct a reality that is conducive to building new systems and structures to support a harmonious life on this planet.

La cardiomyopathie représente un problème de santé publique. Malgré les progrès accomplis dans son traitement, le pronostic demeure sévère, justifiant la recherche permanente d'options thérapeutiques nouvelles. La thérapie cellulaire vise en premier lieu la régénération de zones myocardiques nécrosées. En effet, de nombreuses études effectuées sur des modèles animaux ont démontré qufune greffe cardiaque de cellules souches adultes peut améliorer la fonction ventriculaire mais malheureusement ne permet pas de générer de nouveaux éléments contractiles capables de se connecter au réseau de cellules cardiaques de l'hôte. Toutefois, des données récentes ont montré que l'implantation de patches cardiaques permet de remodeler positivement les ventricules étape nécessaire à une bonne régénération cardiaque. Dans ce contexte, notre objectif principal est la mise au point de sac de cellules souches micro désigné adaptées au traitement global du remodelage cardiaque. Mise en place en collaboration avec l'école normal supérieur des arts décoratifs ces sacs ont était fabriqués à partir d'un matériau le Chitosan remodelé par de nouvelles méthodes de moulage afin de présenter des structurations naturel d'une part en nid d'abeilles que nous espérons va permettre la répartition uniforme des cellules souches et d'autre part, en réplication cardiaque obtenue en moulant directement des cœurs de moutons decellularisés. La fonctionnalité de cette approche à était évaluée par transplantation dans un modèle de souris optimisé dans notre laboratoire. La réalisation de ce projet constitue une des étapes précliniques indispensables avant l'application chez l'homme de ces approches thérapeutiquesBiomimicry is an applied science exploring the potentiel of natural material design, process and System to create tools for therapy. Our research investigated new insights in cardiac scaffold fabrication and design for heart global remodeling treatment using principles from the field of biomimicry. The concept of biomimicry has been developed in many different fields before being used in the present work. The specific aims of this thesis were focused on these two key strategies by applying: (1) biomimetic fabrication to build a honeycomb template scaffold in order to increase the adhesivity of non designed chitosan scaffold to the fibrotic heart;(2) Natural template replication, by imprinting the topographic features of the heart pericardium to create a whole organ template scaffold using decellularize hearts as molds for proper cardiac remodeling treatment. Both approaches allowed us to create chitosan scaffolds with well-defined shape, thickness and surface morphology, Finally, we analysed the potential of these scaffolds as possible cell based products. For that we inseminated the scaffolds with fibroblasts and myoblasts and examinated cell viability, morphology and adhesivness. In addition, we examinated tissue integration potential using biocompatibility assay; for that both scaffolds were transplanted ectopicaily in mice back muscle. Histocompatibility staining, inflammation assays and matrix degradability were analyzed in both cases

Biomimicry is an applied science that derives inspiration for solutions to human problems through the study of natural designs, systems and processes. This thesis represents an investigation into biomimicry and includes the development of a design method based on biomimetic principles that is applied to the design of curved building surfaces whose derived integral structure lends itself to ease of manufacture and construction. Three design concepts are produced that utilize a selection of natural principles of design outlined in the initial biomimetic investigation. The first design visualizes the human genome as a template on which the process of architectural design and construction can be paralleled. This approach utilizes an organizational structure for design instructions, the adherence to an economy of means, and a holistic linking of all aspects of a design characteristic of the genetic parallel. The advancement of the first design concept is illustrated through the use of a particular form of parametric design software known as GenerativeComponents. The second design concept applies the biomimetic design approach outlined in concept one to the development of ruled surfaces with an integral structure in the form of developable flat sheets. The final concept documents the creation of arbitrary curved surfaces consisting of an integral reinforcing structure in the form of folded sheet chevrons.

Full textAbstract:
The future success of American cities depends on the support and improvement of the urban cycling experience. Although cycle-commuting is healthy, sustainable, and fun, cycling in the city is dangerous and stressful, to a degree that limits the number of people willing to adopt the practice. Especially in older cities like Pittsburgh, where archaic infrastructure and narrow streets compound the communication issues between drivers and cyclists, being a cyclist requires a certain level of confidence and risk-taking that many people cannot afford. Improving the safety of this practice through better communication and heightened visibility would increase the quality of the experience and the number of participants. This thesis project explores the opportunities for improving the safety of urban cyclists through the study of time-tested communication strategies exhibited by other organisms and the translation of those strategies into human-specific solutions. Using the algorithmically-based visual strategies of poison dart frogs and the most common colors of the Pittsburgh road environment, I developed highly-dynamic reaction-diffusion patterns that dramatically increase the visibility of cyclists. Using the effective patterns, I prototyped wearables that take into account the inventive spirit of the urban cyclist—first as hand-drawn sketches, then as 3D textile prototypes that highlight the patterns through in silk-screened fabrics. Finally, I evaluated the placement of these wearables on the cyclist, paying close attention to its effects on the visual impact and communicative ability of the cyclist. The wearables proposed in this project will be refined and tested further with the goal of entering production with confidence to serve the Pittsburgh cycling community. Additionally, patterns and regionally-specific color palettes will be developed, ensuring that similar wearables that communicate effectively in specific environments enter other cities and markets, and ultimately save lives.

Full textAbstract:
The ever-increasing nature of consumer demands has forced retailers to adopt 'added value' strategies to ensure their competitive edge in the market. Branding is considered a market differentiator, but alone is not enough to convince consumers to make a purchase. Consumers want more. Trends in the contemporary retail industry show that retail sustainability and retail experience design are two of the most successful added value strategies employed.
This brings forth the issue of the retail sector's resource intensive and wasteful nature. Natural resources are used to produce everything from products and packaging to the physical retail space including the architectural structure, interior finishes and fittings, all for it to be demolished and discarded as waste at the end of its life cycle.
This dissertation explores the value of nature as a model and mentor in the realm of retail design, particularly through application of Biomimetic and Biophilic design theories. Biomimicry is used as a design tool for developing a sustainable retail servicescape that emulates nature's resource efficient and zero-waste principles. Biophilic design strategies are employed towards the development of an in-store retail experience inspired by nature.
Margaret Roberts; a well renowned South African herbalist - specialising in the art of healing with medicinal herbs, is the 'client' for this study. The proposed design intervention is the creation of a skincare servicescape for Margaret Roberts that integrates Biomimicry and Biophilia as an added value strategy.Die immer veranderende aptyt van verbruikers het handelelaars genoop om tradisionele verkoopsdenke te verander en aan te pas ten einde te verseker dat "toegevoegde waarde " ontsluit word in 'n streng kompeterende mark. 'n Handelsmerk word beskou as 'n wesenlikke onderskeier maar is opsigself nie voldoende om verbruikers te oortuig om die produk te bekom nie. Verbruikers verlang meer as dit. Tendense in die kontempor?re verkoops-industrie dui op kleinhandel-volhoubaarheid asook kleinhandel-ontwerp "ondervinding" as twee van die meer suksesvolle strategie? om waarde te ontsluit. Dit plaas die kleinhandel sektor se ho? hulpbron verbruik en vermorsing onder die vergrootglas. Natuurlikke hulpbronne word gebruik, nie net vir die produksie van produkte nie maar ook vir die vervaardiging van verpakking, fisiese handelruimte oprigting insluitende argitektoniese struktuur, binnehuise versierings asook bybehore. Alles net om aan die einde van hul bruikbaarheidslewe afgebreek en weggegooi te word - 'n wesenlikke vermorsing. Hierdie skrywe ondersoek die rol van die natuur as model en mentor in Handelsontwerp met die fokus op die toepassing van Biomimetic en Biophilic ontwerpsbeginsels. Biomimicry word aangewend as 'n ontwerpsinstrument in die ontwikkelling van volhoubaarheids Handels en Dienste-ontwerp wat doeltreffendheid en zero-vermorsing beginsels van die natuur najaag. Biophilic ontwerpsbeginsels word terselfde tyd ook aangewend om die aankoopondervinding in die handelsruimte te ontwikkel en verbeter volgens natuur-geinspireerde beginsels. Margaret Roberts, 'n vernaamde Suid Afrikaanse kruiedeskundige wat spesialiseer in kruiemedisyne, is die kli?nt vir hierdie studie.

Full textAbstract:
Silk has enormous potential as a next-generation material: it is a biopolymer spun from protein at ambient temperature and pressure, and the best spider silks are as strong as steel and tougher than Kevlar. Because of its green production, mechanical robustness, and biocompatibility, silk has been researched for use in a range of engineering and biomedical applications. However, despite exciting recent advances in artificial silk fabrication via recombinant techniques, reserachers remain unable to fully replicate the complex assembly and hierarchical structure of native silks. Herein, we describe our morphological and mechanical characterization of a uniquely simple model silk system that revealed novel aspects of assembly and morphology: the thin ribbon silk spun by the recluse genus of spiders (Loxosceles). We characterized the Loxoscles silk ribbon, which is 7–10 µm wide and only 50–80 nm thick, at molecular-scale resolution using atomic force microscopy (AFM), then designed a custom AFM-based test to probe the silk’s mechanical properties. Our findings revealed a nanofibrillar substructure and mechanical performance typical of other spider silks, as well as hitherto undescribed protrusions (“nanopapillae”) on the surface. to complement these results, we investigated the 5 nm–thin cribellate fibrils spun by the southern house spider, a close relative of Loxosceles, and observed both nanofibrils and nanopapillae. We also assembled silkworm silk using a simple spin-coating routine, revealing nanofibrils in AFM scans that we quantified using extensive imaging analysis. The similarities and differences between these thin silk systems give a blueprint of silk’s core structural constituents and show the effects of thin assembly. Beyond these studies of molecular-scale structure, we discovered that the recluse uses an intricate spinning mechanism to form its ribbons into loops—a previously unknown web organization. By performing mechanical tests of looped silk and designing a mechanical model of the system, we found that introducing sacrificial loops into any fiber can significantly enhance its toughness, and we identified which looping and fiber parameters optimize the effect. We then fabricated a proof of concept—a looped strand of tape—and showed it to be far tougher than non-looped tape of equivalent length. Thus, our research of thin silk systems and our derivation of a bioinspired model have the potential to significantly impact the design of novel artificial silks and ultra-tough fibers.

Full textAbstract:
This research provides an outlook on the use of biomimicry across disciplines, with a particular focus on the application of metal Additive Manufacturing (AM) to fabricate more efficient fin geometries for heat exchangers. By using functional modelling, a denticle from a shortfin mako shark was identified as geometry for a novel 3D fin for a heat exchanger. The shape of the denticle is streamlined and is known to reducing drag; therefore, indicating a possibility of enhancing fluid-to-solid contact for enhanced heat transfer when used as a fin. Initially, the thermo-hydraulic performance of the denticle was numerically evaluated with respect to a rectangular fin, cylindrical fin, and an NACA 0030 fin, using conjugate-heat-transfer simulations on ANSYS-Fluent. Then, A Markforged Metal X printer was used to fabricate the denticle fin with stainless steel 17- 4PH. Thermal and pressure drop experiments were performed to evaluate the thermos-hydraulic performance of the denticle relative to a rectangular fin. Further, a multi-objective gradient based optimisation was performed on the denticle fin by using ANSYS-Fluent. Results demonstrated that over the range of tested Reynolds numbers, 3.9x104 < Re ≤ 9.2x104, mean thermal performance factors of 1.33 and 1.09 were noted for the shape optimised denticle with respect to the rectangular fin, and initial denticle fin, respectively. Finally, the effect of using bio-inspired surface texturing as a technique to further enhance the thermo-hydraulic performance of a single NACA 63-015 fin was investigated experimentally. A mean thermal performance factor of 1.11 was noted for the range of tested Reynolds numbers, which demonstrated that the addition surface textures in the form of shark denticles to a NACA 63-015 profile increased the thermos-hydraulic performance of the fin compared to a smooth one.

Full textAbstract:
Biologically inspired design (BID) is a widespread and growing movement in modern design, pulled in part by the need for environmentally sustainable design and pushed partly by rapid advances in biology and the desire for creativity and innovation in design. Yet, our current understanding of cognition in BID is limited and at present there are few computational methods or tools available for supporting its practice. In this dissertation, I develop a cognitive model of BID, build computational methods and tools for supporting its practice, and describe results from deploying the methods and the tools in a Georgia Tech BID class.
One key and novel finding in my cognitive study of BID is the surprisingly large degree to which biological analogues influence problem formulation and understanding in addition to generation of design solutions. I call the process by which a biological analogue influences the evolution of the problem formulation analogical problem evolution. I use the method of grounded theory to develop a knowledge schema called SR.BID (for structured representations for biologically inspired design) for representing design problem formulations. I show through case study analysis that SR.BID provides a useful analytic framework for understanding the two-way interaction between problems and solutions.
I then develop two tools based on the SR.BID schema to scaffold the processes of problem formulation and analogue evaluation in BID. I deployed the two tools, the four-box method of problem specification and the T-chart method of analogical evaluation, in a Georgia Tech BID class. I show that with minimal training, the four-box method was used by students to complete design problem specifications in 2011 and 2012 with 75% of students achieving better than 80% accuracy. Finally I describe a web-based application for interactively supporting BID practice including problem formulation and analogue evaluation.
Thus, my dissertation develops a cognitive model of analogical problem evolution in BID, a knowledge schema for representing problem formulations, a computational technique for evaluating biological analogues, and an interactive web-based tool for supporting BID practice. Through a better cognitive understanding of BID and computational methods and tools for supporting its practice, it also contributes to computational creativity.

Full textAbstract:
Thesis (PhD)--Stellenbosch University, 2014.ENGLISH ABSTRACT: The work presented in this thesis throws light on the supramolecular approach in exploration of bi-porphyrin nanorods system wherein self-assembly plays an important role. Porphyrin based nanorods were synthesized via self-assembly of meso-tetrakis (4-phenylsulfonicacid) porphyrin dihydrochloride and Sn (IV) tetrakis (4-pyridyl) porphyrin. Understanding the sizes and growth mechanism of the porphyrin nanorods by self-assembly and molecular recognition is essential for their successful implementation in nanodevices. Spectroscopic and microscopic studies were carried out to investigate the effect that time, concentration and solvents have on the fabrication of the porphyrin nanorods by ionic self- assembly. This study demonstrated that aggregates of the di- acid form of meso-tetrakis (4-phenylsulfonic acid) porphyrin dihydrochloride and Sn (IV) tetrakis (4-pyridyl) porphyrin resulted in porphyrin nanorods with diameters between 20 nm and 60 nm, and μm in lengths. Enhanced optical properties illustrated the potential for slightly modifying the method of synthesis to influence the physical and optical properties of porphyrin nanorods. The porphyrin nanorods reflectance data demonstrated that these structures are good absorbers of light and therefore could potentially be used to harvest light. The nonlinear optical (NLO) properties of the porphyrin nanorods were investigated for the first time in this study by second and third harmonic generation techniques. Such study was influenced by the fact that porphyrins have great thermal stability and extended -conjugated macro cyclic ring which give them large nonlinear optical effects. The NLO results showed that the porphyrin nanorods may have many potential uses in photonic applications due to larger third order nonlinear susceptibility. Single molecule spectroscopy was also used to investigate the dynamics of intermolecular and intramolecular processes. Porphyrin nanorods were incorporated into polymer matrices to achieve an arrangement where they can be directly used as a device. The assembly of porphyrin nanorods on track-etched membranes was achieved through altering the surface charge of the respective membranes. Porphyrin nanorods-polymer composites were produced using latex technology and electrospinning techniques. The fibres were characterized with respect to morphology and optical properties.
AFRIKAANSE OPSOMMING: Die werk wat in hierdie tesis beskryf word werp lig op die supramolekulêre benadering in die ondersoek van bi-porfirien nano-silinders waarin self-versameling ‘n belangrike rol speel. Porifirien nano-silinders was voorberei via self-versameling van meso-tetrakis(4-feniel sulfoonsuur) porfirien dihidrochloried en Sn (IV) terakis (4-piridiel) porfirien. Dit is belangrik om die meganismes wat verband hou met die groei en grootte van die nano-silinder struktuur te ondersoek. Dit het ‘n invloed op die self-versameling asook die uiteindelike toepassing. Spectroskopiese en mikroskopiese studies was uitgevoer om die effek van tyd, konsentrasie en oplosmiddel op die selfversamelling te bestudeer. Die studie dui daarop dat bondels van die disuur vorm van meso-tetrakis(4-feniel sulfoonsuur) porfirien dihidrochloried en Sn (IV) terakis (4-piridiel) porfirien het gelei tot porfirien nano-silinders met lengtes tussen 20 nm en 60 nm asook in die mikro meter skaal. Verhoogde optiese eienskappe het die potensiaal om effense veranderinge in die metode om die nano-silinders voor te berei om sodoende ‘n groter invloed op die fisiese en optiese einskappe te hê. Die reflektansie data wys dat hierdie strukture goeie absorbsies van lig toon en daarom geskik sal wees om lig te stoor. Die nie-liniêre optisie (NLO) eienskappe van die profirien nano-silinders was vir die eerste keer ondersoek deur middel van tweed en derde hormoniese generasie tegnieke. Hierdie studie was beïnvloed deur die feit dat porfiriene goeie stabiliteit by hoë temperatuur en ‘n verlengde -gekonjugeerde makro-sikliese ring bevat wat dan groot nie-liniêre optiese effekte gee. Die NLO resultate wys dat die profirien nano-silinders groot potensiaal het in die gebruik van fotoniese toepassings as gevolg van derde orde nie-liniêre vatbaarheid. Enkel molekuul spektroskopie was ook gebruik om die dinamika van intermolekulêre en intramolekulêre prosesse te ondersoek. Porfirien nano-silinders was geïnkorporeer in polimeer matrikse om ‘n eweredige verspreiding te verkry en om direk as ‘n toestel te gebruik. Die versameling van porfirien nano-silinders op baan-ingeëtse membrane was bereik deur die verandering in oppervlak lading van die membrane. Porfirien nano-silinder / polimeer samestellings was verkry deur lateks tegnologie en elektrospin tegnieke. Die vesels was gekarakteriseer in terme van morfologie en optiese eienskappe.

Architecture has been primarily ocularcentric for the last century. This thesis proposes a more sensible approach to architecture. A multisensory experience that gives the user a deeper response to the building. Architecture can activate and engage multiple senses through the revelation of nature such as: wind, light, and shadow.
Architecture has the power to reveal the essence of nature and natural phenomena. It can also become a catalyst to help us understand nature and attain a deeper connection with it and ourselves. Through derived forms and attention to details, architects can capture the essence of nature without direct imitation.
Architecture has always had the power to reveal. The architect must choose what is revealed. This thesis is an exploration into the idea of architecture as a revelation of nature in a specific climate, location, and context to allow the user to become more attuned to nature. Architecture can allow the users to explore and discover nature in a way that was previously ignored or overlooked, or perhaps it can reveal a phenomenon for the first time.
Architecture can reveal nature through: orientation, material choices, form, function, openings, details, and spacing. Allowing natural phenomena to be a part of the design process creates a building attuned to nature. These revelations can occur with careful consideration to components, conditions, and details such as: wind, light, shadow, and structure. In order to achieve these, special consideration must be give to the tectonic and stereotomic construction.Master of Architecture

A disponibilidade de recursos naturais é comprimida pelo crescimento populacional e por padrões inadequados de produção, fazendo com que as organizações procurem referências para crescer de modo sustentável. Para isso, é necessário readequar as indústrias, repensando as lideranças e o impacto de cada ação para o planeta. Os negócios dependem da natureza, e a busca por soluções sustentáveis é, além de uma boa prática, condição necessária para a manutenção da competitividade. O Método de Pensamento Biomimético busca na natureza a fonte de inspiração para a criação e a resolução de desafios; no entanto, o atual formato do Método de Pensamento Biomimético nem sempre é convidativo aos que não enxergam a natureza como princípio de orientação na busca de soluções sustentáveis ou aos que não se sentem confortáveis com modelos disruptivos de inovação. O Método do Pensamento Sistêmico permite enxergar de forma holística e integrada tanto o contexto como o impacto de uma solução e, ainda, oportuniza a quebra de modelos mentais limitantes; todavia, não direciona a criação de produtos, sistemas ou processos, lacuna que busca ser suprida pelo Método de Pensamento Biomimético. Logo, visando ao desenvolvimento sustentável por meio de soluções sustentáveis, esta pesquisa tem como objetivo integrar o Método de Pensamento Biomimético ao Método de Pensamento Sistêmico, dando origem ao Método Biomimético Sistêmico. Para tanto, o método de pesquisa utilizado foi a Design Science Research (DSR). Os resultados desta pesquisa indicam que o método proposto é aceito por especialistas de ambas as áreas e é adequado para encontrar soluções sustentáveis e sistêmicas. Nesse sentido, contribui para o desenvolvimento sustentável, configurando um passo importante para o avanço da inovação e sustentabilidade de forma consciente por meio de impactos positivos para as empresas e para a natureza.
While the availability of natural resources is constrained by population growth and inadequate production processes, organizations still look for references to grow in a sustainable way. Therefore, it is necessary to reshape industries, rethink leaderships and become aware of the impact of every action to the planet. Given the dependence that businesses have of nature, the search for sustainable solutions is, besides a good practice, a necessary condition for maintaining competitiveness. The Biomimicry Thinking Method ensures that the final design solution is likely to truly emulate nature, however, the current format of the Biomimicry Thinking Method is not always inviting to those who do not see nature as a guiding principle to find sustainable solutions or also for those who do not feel comfortable with innovative technology models. Meanwhile, the Systems Thinking Method gives a holistically view and integrate both the context and the impact of a solution and, opportunistically, the breaking of limiting mental models, however it is not for the design of products, systems and processes. Therefore this research aiming at sustainable development through sustainable solutions, aimed to integrate the Biomimicry Thinking Method with the Systems Thinking Method, giving rise to the Systemic Biomimetic Method. To support this study, the research method used was the Design Science Research (DSR). The results of this research indicate good acceptance of the method between experts from both areas and, in addition, it can be concluded that the developed method is suitable for find sustainable systemic solutions and to contribute to sustainable development, and sets up an important step in advancing of innovation and sustainability in a conscious way through the positive impacts for companies and nature.

Le biomimétisme ou conception bio-inspirée est une approche qui propose l'utilisation du vivant en tant que source d'inspiration pour améliorer ou concevoir de nouvelles technologies. Intégrer la conception bio-inspirée au processus d'innovation des entreprises pourrait ainsi permettre la génération de concepts à la fois innovants et durables.Cette thèse, réalisée au sein de Renault avait deux objectifs: comprendre les mécanismes de la conception bio-inspirée et les appliquer à un cas concret dans l'automobile pour stimuler la génération de concepts en rupture.Pour comprendre les mécanismes de la bio-inspiration, nous nous sommes appuyés sur la littérature scientifique ainsi que sur les inventions et concepts bio-inspirés. Pour analyser le raisonnement de conception de ces exemples, nous avons choisi une théorie de la conception, la théorie C-K. Le cadre issu de la théorie C-K nous a permis de proposer un modèle général pour la conception bio-inspirée.Nous avons appliqué ce modèle au champ d'innovation du véhicule décarboné. Ce champ traite des questions liées au développement d'innovations permettant aux véhicules de réduire leur empreinte environnementale, principalement par la réduction des émissions de dioxyde de carbone (CO2), un puissant gaz à effet de serre qui contribue également au phénomène du changement climatique. L'identification des voies où la rupture serait nécessaire a débuté par la réalisation d'un arbre des concepts, à l'aide des connaissances internes disponibles en entreprise auprès des experts leaders. Un travail de réorganisation de ces concepts et la création d'une base de connaissances rassemblant articles scientifiques et expertises sur le sujet des émissions de gaz à effet de serre ont été effectués. Ce travail a permis de cartographier le champ d'innovation du véhicule décarboné. Les véhicules multi-énergies ont été la voie choisie pour la recherche de concepts bio-inspirés.Une recherche générale sur l'énergie dans le vivant nous a conduits à identifier l'énergie dans les cellules animales et particulièrement chez les humains comme une base de connaissances biologiques particulièrement intéressante. L'énergétique humaine possède un certain nombre de propriétés qui pourraient permettre une révision des connaissances sur les véhicules multi-énergie, notamment sur le stockage et la transformation d’énergie. La performance sportive humaine s'est aussi révélée être une base de connaissances intéressante par les différentes techniques utilisées pour les entrainements et en course afin de mieux mobiliser des sources d'énergie.L'application du modèle du processus de bio-inspiration avec C-K nous a conduit à formuler un concept inspiré des observations réalisées sur des coureurs pendant des courses supérieures à 1 500m. En effet, les profils de vitesse enregistrés pour des athlètes indiquent qu'une variation de vitesse est choisie par le coureur pour lui permettre de mieux utiliser ses réserves anaérobies limitées. Pour un véhicule, ceci pourrait impliquer qu'une variation de vitesse pourrait conduire à des meilleurs résultats en termes de consommation de carburant qu'une vitesse stabilisée. Ce concept a été exploré dans cette thèse à l’aide de la réalisation d'essais sur piste et des simulations avec des modèles numériques. Ces explorations montrent le potentiel de ce concept pour des véhicules conventionnels et aussi ses limitations.Ces travaux ouvrent des perspectives pour la gestion d'énergie des véhicules considérant la façon dont l'énergie est produite, stockée et utilisée chez le vivant. Les systèmes énergétiques étudiés par la physiologie humaine représentent un terrain intéressant pour le développement de véhicules adaptables à différents cas d'utilisation. De plus, l'étude du processus de la bio-inspiration a permis d'éclairer les raisons de faire appel à cette démarche et les conditions qui permettraient son application plus systématique dans les processus d'innovation en entrepriseBiologically inspired design, also called bioinspired design, biomimetics or biomimicryproposes the use of Nature, or biological knowledge, as a source of inspiration to improve orconceive new designs. Integrating the biologically inspired design approach into theinnovation process of companies could then allow the generation of more innovative and sustainable concepts.This thesis, realized during three years at a French automaker (Renault) research and development department had two objectives: to understand the mechanisms of the biologically inspired design and to apply this approach to a case belonging to an innovation field of the automotive sector.In order to understand the mechanisms of biologically inspired design we studied theliterature about bio-inspired concepts and inventions.We have chosen a design theory, the C-K theory, to analyse the design process of these literature examples. This allowed us to propose a model for bio-inspiration.We applied this model inspired by the C-K theory to the low carbon vehicle innovation field.This field includes the development of innovations allowing passenger cars to reduce theirenvironmental footprint, mainly the reduction of carbon dioxide (CO2) emissions. Thecarbon dioxide is a greenhouse gas that contributes to the climate change phenomena. Theidentification of the path where concept partitioning is required in this field began with theconstruction of a concepts space, using knowledge of company experts on the subject.Reorganizing these concepts and building a knowledge base on the strategies for CO2 emissions allowed us to map this innovation field. The vehicles with more than oneenergy source, such as electrified internal combustion engine vehicles and hybrid vehicleswere the path chosen for the research of bio-inspired concepts.A research about energy in nature led us to identify the energy in animal cells, particularlythose in humans as an interesting biological knowledge base. Human energy properties suchas cells with more than one kind of energy storage, with at least two metabolic pathways torecharge these stores are interesting to revise the knowledge about energy store andconversion in multi-energy vehicles. Besides, the human sportive performance has appearedto be an interesting knowledge base, as the training techniques and the running techniquesduring a race can influence the way athletes use their energy.These two biological bases have led us to formulate a bio-inspired concept based on therunning patterns observed in runners during races superior to 1500~m. The speed profilesrecorded show a spontaneous speed variation chosen by the runner, in order to better use itslimited anaerobic energy stores. For a vehicle, this could mean that varying its speed couldallow a lower fuel consumption than using a constant speed. This bio-inspired concept wasexplored in this thesis with the realization of tests in a dedicated test track and simulations. These tests show the potential of this concept for conventional vehicles and its limitations.This work opens the way for analysing the vehicle energetics in the light of human energetics.The versatility of human activities could help on the development of vehicles adapting todifferent use cases. Further research could also use the knowledge about the dynamic modelling of energy in vehicles to complete the empirical approaches used to model the human energy management, allowing a betteroptimization of running strategies. The study of the bio-inspiration process using a designtheory also allowed a better comprehension of the reasons for using this approach and of theconditions for successfully applying it in the innovative process of a company

Full textAbstract:
Analogies play a well-noted role in innovative design. Analogical reasoning is central to the practices of design-by-analogy and bio-inspired design. In both, analogies are used to derive abstracted principles from prior examples to generate new design solutions. While numerous laboratory and classroom studies of analogy usage have been published, relatively few studies have systematically examined real-world design-by-analogy to describe its characteristics and impacts. To better teach design-by-analogy and develop support tools for engineers, specific insights are needed regarding, for example, what types of product advantages are gained through design-by-analogy and how different design process characteristics influence its outcomes. This research comprises two empirical product studies which investigate analogical inspiration in real-world design to inform the development of new analogy methods and tools. The first, an exploratory pilot study of 57 analogy-inspired products, introduces the product study method and applies several categorical variables to classify product examples. These variables measure aspects such as the composition of the design team, the driving approach to analogical reasoning, and the achieved benefits of using the analogy-inspired concept. The full scale study of 70 analogy-inspired products uses formal collection and screening methods and a refined set of classification variables to analyze examples. It adopts a cross-sectional approach, using statistical tests of association to detect relationships among variables. Combined, these surveys of real-world analogy-inspired innovation inform the development of analogy tools and provide a general account of distant analogy usage across engineering disciplines. The cross-sectional product study method demonstrated in this work introduces a valuable tool for investigating factors and impacts of real-world analogy usage in design.

Large particles such as falling raindrops can weigh up to fifty times a mosquito. Mosquitoes survive such impacts by virtue of their low mass and strong exoskeleton. Smaller particle sizes, as present in fog and insecticide, pose the greatest danger. Mosquitoes cannot fly through seemingly innocuous household humidifier fog or other gases with twice the density of air. Upon landing, fog accumulates on the mosquito body and wings, which in small quantities can be shaken off in the manner of a wet dog. Large amounts of dew on the wings create a coalescence cascade ultimately folding the wings into taco shapes, which are difficult to dry. The insights gained in this study will inform the nascent field of flapping micro-aerial vehicles.

Denna uppsats är ett examensarbete på 22,5 Hp, gjort av Natalie Pålsson, student på produktdesignprogrammet på Malmö Högskola, under våren 2013.Projektet handlade om att undersöka möjligheten till att skapa en ljuskälla utan elektricitet. Syftet med projektet var att uppmärksamma problematiken av den höga energiförbrukningen av ljuskällorna i belysning. Projektet hade under hela dess gång ett biomimetiskt förhållningssätt och under förstudien gjordes en grundlig studie av ämnet biomimetik. Biomimetik innebär att man som designer lär och inspireras av naturen i sin produktutveckling. Förstudien behandlade även ämnet naturens ljus och då framför allt bioluminiscens som valdes som ljuskälla i armaturen. Utifrån en intervju med Lars Olof Björn, pensionerad professor i biologi, så togs ett beslut att använda levande organismer i armaturen eftersom bioluminiscens är svårt att framställa på kemisk väg. Under studierna av bioluminiscens så framkom det att det finns en bioluminiscent alg, dinoflagellat som skulle vara lämplig att använda som ljuskälla. Dinoflagellater avger ett bioluminiscent ljus då de sätts i rörelse, vilket användes som en sorts strömbrytare i produkten. Resultatet blev lyktan Lumi oh! En lykta, utformad som ett timglas som ser ut som två droppar som i sitt möte bildar en virvel. När lyktan vänds upp och ner, virvlar algerna ner och börjar då lysa, vilket de gör så länge de är satta i rörelse.Projektets mål var att det skulle resultera i ett produktkoncept, därför presenteras slutresultatet i form av en utseendemodell.This diploma work (22,5 ECTS) at bachelor level is made by Natalie Pålsson, student at the Product design program at Malmö University, in the spring of 2013. The project explored the possibility of creating light without electricity. The purpose of the project was to highlight the problem of the high energy consumption of our current lightsourses. The project had a biomimetic approach and a thourough study of the subject was made. Biomimicry means that designers learn and get inspired by nature in their development of products. A study about natural light was made, especially bioluminescence, since that was the choice of lightsource. Based on an interview with Lars Olof Björn, a retired proffessor in Biology, it was decided to use living organisms in the lantern, since bioluminescence is difficult to produce chemically. The research regarding bioluminescence showed that there is a bioluminescent algae, called dinoflagellate, that would be suitable for use as a light source. Dinoflagellates emit a bioluminescent light when they are put in motion, which was used as a sort of on and off switch in the product. The project resulted in the lantern Lumi oh! A lantern, shaped like an hour glass which looks like two drops, that forms a swirl where they meet. When the lantern is turned upside down, the alge swirls down and starts to glow, for as long as they are set in motion. The result of the project was to be illustrated as a product concept and is presented as a prototype that shows the form but not the function.

Full textAbstract:
Thesis (MTech (Industrial Design))--Cape Peninsula University of Technology, 2019In this research study Biomimicry and sustainable product-service systems (S.PSS) are explored in order to examine the Design for Sustainability (DfS) paradigm through a set of eight guidelines. It is argued that Biomimicry holds the blueprint to a design strategy that is more environmentally sustainable. This research study demonstrates that sustainability’s triple bottom line can be achieved by combining Biomimicry’s potential for environmental sustainability with S.PSS’s potential to foster social and economic sustainability. The study describes a behavioural change towards sustainability and proposes design education as a strategy to nurture sustainable design praxis. It is shown that the sustainable design praxis of student groups leads to behavioural shifts towards sustainability through design education. Industrial design students at the Cape Peninsula University of Technology in South Africa engaged in a short course on DfS and their design outcomes provided the data sets that have been analysed through inductive thematic analysis. The course was used as a case study from which theory was built. This specific research approach is called theory building from case studies. The appendices are included to supply additional evidence of where and how the data collection happened, and provides depth and insight into the projects. The richness and scope of the research study is supported by the appendices - it is for this reason that the rather sizable addition was included. It is through the thematic analysis that a set of eight guidelines were developed from the data and measured against a framework of critical citizenship in order to evaluate the societal behavioural shift to a more holistic approach to DfS. This thesis draws on existing fields of study within the DfS paradigm and integrates several fields of study in order to contribute to the discourse of a holistic approach to DfS.
