A Study on Phase Change Materials at Low Thermal Mass with Micro-Electro-Mechanical Resonators
DownloadSpring 2020
Micro-electromechanical systems or MEMS is a modern technology used to create tiny, integrated devices or systems that combine mechanical and electrical components. These miniaturized devices can sense, control and actuate on the micro and nano scales, and generate observable effects on the macro...

An examination of linking and blocking procedures for use in deflection cantilever array-based protein detection
DownloadFall 2011
In this project common linking and blocking procedures were examined for use in multiplexed deflection cantilever array-based detection of proteins. A human interferon gamma (INF-γ) enzyme-linked immunosorbent assay (ELISA) kit was used to evaluate the effectiveness of the linking and blocking...

Fall 2011
High aspect ratio microelectromechanical structures have been found, in the literature, to collapse due to capillary forces of liquids. In this dissertation, mathematical models are developed to study (i) the collapse of a microstructure represented by a double cantilevered beam (DCB) with a free...

Design and Fabrication of Micro-electro-mechanical Systems Actuators for Application in External Cavity Tunable Lasers
DownloadFall 2014
The limited availability of rugged and economical infra-red laser sources that can be tuned over a certain wavelength range is still a bottleneck for widespread application of spectroscopic methods to environmental, industrial, and medical trace gas monitoring. Conventional semiconductor lasers...

Design and Microfabrication of Robust and Highly Integrated Thermal Lab-On-A-Chip Polymeric Systems for Genetic Diagnosis
DownloadSpring 2014
The lab-on-chip (LOC) technology could transform and greatly enhance the health care system by making genetic diagnosis tests fast, accurate and readily accessible. However, most LOC systems are not prepared to resist variations of their external environment, as they depend upon many...

Development of a MEMS 3D Stress Sensor Using Strain Engineering for Out of Plane Stress Applications
DownloadSpring 2020
This work aims to enhance the performance of a MEMS-based 3D piezoresistive sensor, which has the capability of extracting the six temperature-compensated stress components. That sensor is made of an n-type piezoresistive element that has low pressure/out-of-plane piezoresistive (PR) coefficient,...
