Abstract (sommario):

The tight integration of actuation, sensing, and communication capabilities into origami robots enables the development of new-generation functional robots. However, this task is challenging because the conventional materials (e.g., papers and plastics) for building origami robots lack design opportunities for incorporating add-on functionalities. Installing external electronics requires high system integration and inevitably increases the robotic weight. Here, a graphene oxide (GO)–enabled templating synthesis was developed to produce reconfigurable, compliant, multifunctional metallic backbones for the fabrication of origami robots with built-in strain sensing and wireless communication capabilities. The GO-enabled templating synthesis realized the production of complex noble metal origamis (such as Pt) with high structural replication of their paper templates. The reproduced Pt origami structures were further stabilized with thin elastomer, and the Pt-elastomer origamis were reconfigurable and served as the multifunctional backbones for building origami robots. Compared with traditional paper and plastic materials, the reconfigurable Pt backbones were more deformable, fire retardant, and power efficient. In addition, the robots with conductive Pt-elastomer backbones (Pt robots) demonstrated distinct capabilities—such as on-demand resistive heating, strain sensing, and built-in antennas—without the need for external electronics. The multifunctionality of Pt robots was further demonstrated to extend beyond the capabilities of traditional paper-based robots, such as melting an ice cube to escape, monitoring/recording robotic motions in real time, and wireless communications between robots. The development of multifunctional metallic backbones that couple actuation, sensing, and communication enriches the material library for the fabrication of soft robotics toward high functional integration.

Abstract (sommario):

Robots autonomously interact with their environment through a continual sense–decide–respond control loop. Most commonly, the decide step occurs in a central processing unit; however, the stiffness mismatch between rigid electronics and the compliant bodies of soft robots can impede integration of these systems. We develop a framework for programmable mechanical computation embedded into the structure of soft robots that can augment conventional digital electronic control schemes. Using an origami waterbomb as an experimental platform, we demonstrate a 1-bit mechanical storage device that writes, erases, and rewrites itself in response to a time-varying environmental signal. Further, we show that mechanical coupling between connected origami units can be used to program the behavior of a mechanical bit, produce logic gates such as AND, OR, and three input majority gates, and transmit signals between mechanologic gates. Embedded mechanologic provides a route to add autonomy and intelligence in soft robots and machines.

Abstract (sommario):

ABSTRACTA major challenge in nanofabrication is the manipulation and exact placement of nano-objects on a specific template. Artificial DNA nanostructures such as DNA origami have garnered significant interest as templates for incorporating nanomaterials at precise sites while the structures are self-assembled. This work shows the usage of the DNA origami technique in the design and fabrication of nanostructures with the shapes of a circle and a triangle using the third part of the M13 virus genome, named mini-M13, as a scaffold. These DNA origami templates were modified to have DNA binding sites with a uniquely coded sequence. This method is used to attach 5 nm gold nanoparticles functionalized with the complementary DNA sequence. Two new metallic nanostructures with different nanoparticle arrays having minimum size but recognizable morphology are provided. The formation and dimensions of the nanostructures were verified using AFM and agarose gel electrophoresis.

Abstract (sommario):

Molecular simulations using coarse-grained models allow the structure, dynamics and mechanics of DNA origamis to be comprehensively characterized. Here, we focus on the free-energy landscape of a jointed DNA origami that has been designed to exhibit two mechanically stable states and for which a bistable landscape has been inferred from ensembles of structures visualized by electron microscopy. Surprisingly, simulations using the oxDNA model predict that the defect-free origami has a single free-energy minimum. The expected second state is not stable because the hinge joints do not simply allow free angular motion but instead lead to increasing free-energetic penalties as the joint angles relevant to the second state are approached. This raises interesting questions about the cause of this difference between simulations and experiment, such as how assembly defects might affect the ensemble of structures observed experimentally.

Abstract (sommario):

ABSTRACTWe discuss the self-folding of patterned metallic sheets using both differential stress and surface forces. The advantageous characteristics of the technique include, (a) The creation of 3D patterned corrugated metamaterials with pattern resolution limited only by that of planar lithography. Since planar lithography is highly versatile, a variety of patterns with different sizes and shapes can be formed. (b) The hands-free and wire-free self-folding of these materials use two orthogonal forces derived from the release of residual stress and the minimization of surface tension. Hence, this process is highly parallel and scalable allowing such materials to be mass produced. (c) Finally, the edges of the materials self-align and seal due to capillary forces of the liquid hinges—this self-sealing enhances overall rigidity and strength of the materials.Consequently, the self-folding of patterned and sealed “egg-crate” shaped metamaterials was realized. Patterns were incorporated in the form of “smart” patches on the walls of the egg-crates which can be selectively functionalized with biomolecules. Apart from the intellectual appeal of these hands-free, self-sealing materials, we envision applicability of these egg-crate like microstructures in lab-on-a-chip assays as functionalized microwells and as light weight mechanical metamaterials.

Abstract (sommario):

AbstractMicroorganisms can be present in common equipment of practice, which spread Healthcare-associated infections (HALs), generating major health issues, not only in the hospital environment but outside as well. Especially in this impending crisis due to SARS CoV-19 virus, disinfection (in general) turns out to be of paramount importance and portable disinfection in particular. The rampant spread of the COVID 19 virus, has pushed thinkers to come up with unique disinfection solutions that can help curb the spread of the virus in other places other than the medical facilities. The article aims to establish a design of a portable ultraviolet c disinfectant device that is based on the core principles of origami- the ancient Japanese art of paper folding. Resorting to origami has helped to make the device ultra-portable, robust and can be easily manufactured in order to be commercially produced as an inexpensive alternative to the cost portable disinfection devices in the market.

Abstract (sommario):

The traditional waterbomb origami, produced from a pattern consisting of a series of vertices where six creases meet, is one of the most widely used origami patterns. From a rigid origami viewpoint, it generally has multiple degrees of freedom, but when the pattern is folded symmetrically, the mobility reduces to one. This paper presents a thorough kinematic investigation on symmetric folding of the waterbomb pattern. It has been found that the pattern can have two folding paths under certain circumstance. Moreover, the pattern can be used to fold thick panels. Not only do the additional constraints imposed to fold the thick panels lead to single degree of freedom folding, but the folding process is also kinematically equivalent to the origami of zero-thickness sheets. The findings pave the way for the pattern being readily used to fold deployable structures ranging from flat roofs to large solar panels.

Abstract (sommario):

Biosensors are small but smart devices responding to the external stimulus, widely used in many fields including clinical diagnosis, healthcare and environment monitoring, etc. Moreover, there is still a pressing need to fabricate sensitive, stable, reliable sensors at present. DNA origami technology is able to not only construct arbitrary shapes in two/three dimension but also control the arrangement of molecules with different functionalities precisely. The functionalization of DNA origami nanostructure endows the sensing system potential of filling in weak spots in traditional DNA-based biosensor. Herein, we mainly review the construction and sensing mechanisms of sensing platforms based on DNA origami nanostructure according to different signal output strategies. It will offer guidance for the application of DNA origami structures functionalized by other materials. We also point out some promising directions for improving performance of biosensors.

Abstract (sommario):

Origami, the ancient art of folding thin sheets, has attracted increasing attention for its practical value in diverse fields: architectural design, therapeutics, deployable space structures, medical stent design, antenna design and robotics. In this survey article, we highlight its suggestive value for the design of materials. At continuum level, the rules for constructing origami have direct analogues in the analysis of the microstructure of materials. At atomistic level, the structure of crystals, nanostructures, viruses and quasi-crystals all link to simplified methods of constructing origami. Underlying these linkages are basic physical scaling laws, the role of isometries, and the simplifying role of group theory. Non-discrete isometry groups suggest an unexpected framework for the design of novel materials. This article is part of the theme issue ‘Topics in mathematical design of complex materials’.

Abstract (sommario):

Three-dimensional (3D) origami, which can generate a structure through folding a crease pattern on a flat sheet of paper, has received considerable attention in art, mathematics, and engineering. With consideration of symmetry, the user can efficiently generate a rational crease pattern and make the fabricated shape stable. In this paper, we focus on a category of axisymmetric origami consisting of triangular facets and edit the origami in 3D space for expanding its variations. However, it is difficult to retain the developability, which requires the sum of the angles around each interior vertex needing to equal 360 degrees, for designing origami. Intersections occur between crease lines when such a value is larger than 360 degrees. On the other hand, blank spaces (unfolded areas) emerge in the crease pattern when the value is less than 360 degrees. The former case is difficult to generate a realizable shape due to the crease lines are intersected with each other. For the latter case, however, blank spaces can be filled with crease lines and become a part of the origami through tucking. Here, we propose a computational method to add flaps or tucks on the 3D shape, which contains non-developable interior vertices, for achieving the resulting origami. Finally, on the application side, we describe a load-bearing experiment on a stool shape-like origami to demonstrate the potential usage.

Abstract (sommario):

Applications of aerial robots are progressively expanding into complex urban and natural environments. Despite remarkable advancements in the field, robotic rotorcraft is still drastically limited by the environment in which they operate. Obstacle detection and avoidance systems have functionality limitations and substantially add to the computational complexity of the onboard equipment of flying vehicles. Furthermore, they often cannot identify difficult-to-detect obstacles such as windows and wires. Robustness to physical contact with the environment is essential to mitigate these limitations and continue mission completion. However, many current mechanical impact protection concepts are either not sufficiently effective or too heavy and cumbersome, severely limiting the flight time and the capability of flying in constrained and narrow spaces. Therefore, novel impact protection systems are needed to enable flying robots to navigate in confined or heavily cluttered environments easily, safely, and efficiently while minimizing the performance penalty caused by the protection method. Here, we report the development of a protection system for robotic rotorcraft consisting of a free-to-spin circular protector that is able to decouple impact yawing moments from the vehicle, combined with a cyclic origami impact cushion capable of reducing the peak impact force experienced by the vehicle. Experimental results using a sensor-equipped miniature quadrotor demonstrated the impact resilience effectiveness of the Rotary Origami Protective System (Rotorigami) for a variety of collision scenarios. We anticipate this work to be a starting point for the exploitation of origami structures in the passive or active impact protection of robotic vehicles.

Abstract (sommario):

Latar belakang: Ketika anak sakit dan mengharuskan dirawat di rumah sakit, membuat cemas anak dan keluarga karena harus berusaha beradaptasi dengan lingkungan asing. Salah satu intervensi keperawatan untuk membantu mengurangi kecemasan pada anak selama menjalani hospitalisasi adalah terapi bermain origami. Tujuan penelitian: menganalisis rerata tingkat kecemasan sebelum dan sesudah diberikan terapi origami pada anak usia prasekolah yang menjalani prosedur invasif infus saat hospitalisasi di Ruang Anak RSUD 45 Kuningan. Metode penelitian: jenis penelitian ini adalah Pra Eksperimen dengan rancangan One Group Pretest And Posttest. Jumlah sampel dalam penelitian ini sebanyak 15 responden dengan menggunakan teknik Purposive Sampling. Pengambilan data dilakukan dengan cara mengukur tingkat kecemasan sebelum dan sesudah diberikan terapi bermain origami yang diukur menggunakan Preschool Anxiety Scale-Revised (2010). Selanjutnya data diolah dan dianalisis menggunakan uji Wilcoxon Signed Rank-test. Hasil penelitian menunjukkan bahwa rerata tingkat kecemasan responden sebelum diberikan intervensi adalah sebesar 1,93 dan rerata sesudah diberikan intervensi terapi bermain origami adalah sebesar 1,20. Selisih rata-rata tingkat kecemasan sebelum dan sesudah dilakukan terapi adalah 0,73. Hasil uji statistik wilcoxon tentang pengaruh terapi bermain origami terhadap penurunan tingkat kecemasan pada anak prasekolah yang menjalani hospitalisasi dengan tingkat kepercayaan 95% (α = 0,05) sebesar P value (0,002) dengan demikian p value < 0,05), maka H0 ditolak. Hal ini berarti terdapat perbedaan tingkat kecemasan sebelum dan sesudah diberikan terapi bermain origami. Sehingga dapat disimpulkan bahwa ada pengaruh pemberian terapi bermain origami terhadap tingkat kecemasan anak yang menjalani prosedur invasif infus saat hospitalisasi di rumah sakit. Diharapkan hasil penelitian ini dapat dikembangkan oleh peneliti lain terkait metode adjuvant lain yang dapat menurunkan tingkat kecemasan pada anak sebagai tindakan atraumatic care
