Abstract:
This thesis documents the design, manufacture and testing of a passive and non-invasive micro-scale planar particle-from-fluid filter for segregating cell types from a homogeneous suspension. The microfluidics system can be used to separate spermatogenic cells from testis biopsy samples, providing a mechanism for filtrate retrieval for assisted reproduction therapy. The system can also be used for point-of-service diagnostics applications for hospitals, lab-on-a-chip pre-processing and field applications such as clinical testing in the third world. Various design concepts are developed and man

Abstract:
Modern day engineering systems research presently lacks techniques to exploit the unique properties of many nanomaterials; coupled with this challenge exists the need to interface these nanomaterials with microscale and macroscale platforms. A nanomaterial of particular interest is the carbon nanotube (CNT), due to its enhanced physical properties. In addition to varied electrical properties, the CNT has demonstrated high thermal conductivity and tensile strength compared to conventional fiber materials. CNTs are beginning to see commercial applications in areas in which sufficient study ha

Abstract:
Cancer metastasis, the departure of cancer cells from the primary tumors and their spread to distant sites, is responsible for 90% of cancer related deaths. Thus, understanding the initial process which leads to cancer metastasis in the later stage and stopping the spread in the initial stage deems necessary. In spite of significant progress in diagnosis and treatment, there is still the need for robust and easy to use drug assessment methods. In this work we present two approaches for this purpose: a microengineered Boyden chamber, and a dielectrophoresis-based platform for cell characterizat

Abstract:
Controlling uncertainties is a challenging aspect in design and manufacturing of microsystems. As microsystems are characterised by features in the micro domain, product development and manufacturing processes are applied at the boundaries of their operational areas. In combination with many disciplines (mechanical, electrical, software, chemical etc.) and little standardisation, it causes microsystems development to be more time and cost intensive than products in the macro domain. Development of microsystems benefits from a concurrent approach of product and production design. Uncertainties

Bioimpedance presents a versatile, label-free means of monitoring biological cells and their responses to physical, chemical and biological stimuli. Breast cancer is the second most common type of cancer among women in the United States. Although significant progress has been made in diagnosis and treatment of this disease, there is a need for robust, easy-to-use technologies that can be used for the identification and discrimination of critical subtypes of breast cancer in biopsies obtained from patients. This dissertation makes contributions in three major areas towards addressing the goal.

Abstract:
Cancer metastasis is the leading cause of death related to cancer diseases. Once the cancer cells depart the primary tumor site and enter the blood circulation, they spread through the body and will likely initiate a new tumor site. Therefore, understanding the cell migration and stopping the spread in the initial stage is the utmost of importance. In this dissertation, we have proposed a 3-D microenvironment that (partially) mimics the structures, complexity and circulation of human organs for cell migration studies.

This research investigates how to draw energy from a distant emanating and alternating (i.e., AC) magnetic source and deliver it to a battery (i.e., DC). The objective is to develop, design, simulate, build, test, and evaluate a CMOS charger integrated circuit (IC) that wirelessly charges the battery of a microsystem. A fundamental challenge here is that a tiny receiver coil only produces mV's of AC voltage, which is difficult to convert into DC form. Although LC-boosted diode-bridge rectifiers in the literature today extract energy from similar AC sources, they can do so only when AC voltages

Abstract:
Recent advances in the miniaturization, functionality, and integration of integrated circuits and packages, such as the system-on-package (SOP) methodology, require increasing use of microvias that generates vertical signal paths in a high-density multilayer substrate. A scanning projection excimer laser system has been utilized to fabricate the microvias. In this thesis, a novel technique implementing statistical experimental design and neural networks (NNs) is used to characterize and model the excimer laser ablation process for microvia formation. Vias with diameters from 10 50 micrometer

Abstract:
Ce travail de thèse s'inscrit dans le cadre général du développement de micro-actionneurs MEMS, à bas coût et de technologie simple, pour de futures applications dans le domaine de la microfluidique, notamment. La motivation de ce travail est d'évaluer la faisabilité d'un micro-actionneur électrostricitf à base de film mince polymère électroactif nanocomposite. Le polyuréthane, chargé en nanoparticules de carbone ou carbure de fer, encore peu étudié mais aux propriétés électrostrictives prometteuses, est choisi comme matériau à intégrer dans une filière MEMS silicium classique.

Abstract:
Sveriges landsting har börjat införa nya kliniska informationssystem som komplement till sina elektroniska patientjournaler. Målet är att kunna förnya och effektivisera existerande system och processer, sänka sjukvårdkostnader samt öka patientsäkerhet och kvalité i vården. Trots betydande investeringar i nya kliniska informationssystem har inga övertygande bevis kunnat presenteras för systemens övergripande effekter i organisationen. Ny forskning anser att detta huvudsakligen beror på en trög användning av nya informationssystem som varken är kompatibla eller lätt att använda, samt att verksam

Abstract:
With the completion of the human genome sequencing project, attention is currently shifting toward understanding how genetic variation, such as single nucleotide polymorphism (SNP), leads to disease. To identify, understand, and control biological mechanisms of living organisms, the enormous amounts of accumulated sequence information must be coupled to faster, cheaper, and more powerful technologies for DNA, RNA, and protein analysis. One approach is the miniaturization of analytical methods through the application of microfluidics, which involves the manipulation of fluids in micrometer-size

This dissertation thesis deals with design of new functional blocks usable in area of analogue signal processing, focusing on sensor signal processing. Versatility of these circuits will find applications in programmable analogue array structures that will be possible to control and configure via a digital signal. Hereby build-up array would be fully a reconfigurable digital control system for sensor signal processing and usable for a wide range of different sensors. It offers possibility to build-up a control code for each specific sensor system, with which it would be possible to achieve opt

Abstract:
The field of micro total analysis systems (μTAS) aims at developments toward miniaturized and fully integrated lab-on-a-chip systems for applications, such as drug screening, drug delivery, cellular assays, protein analysis, genomic analysis and handheld point-of-care diagnostics. Such systems offer to dramatically reduce liquid sample and reagent quantities, increase sensitivity as well as speed of analysis and facilitate portable systems via the integration of components such as pumps, valves, mixers, separation units, reactors and detectors. Precise microfluidic control for such systems has

Les matériaux piézoélectriques, comme le titanate-zirconate de plomb Pb(ZrxTi1-x)O3 (PZT), l’oxyde de zinc ZnO, ainsi que la solution solide de Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT), sont actuellement l’objet d’études de plus en plus nombreuses à cause de leurs applications innovantes dans les systèmes micro-électromécaniques (MEMS). Afin de les intégrer sur substrat de silicium, certaines précautions doivent être prises en compte concernant par exemple des couches tampon, les électrodes inférieures. Dans cette thèse, des films piézoélectriques (PZT et PMN-PT) ont été épitaxiés avec succès sous for
