An Investigation of Using n-Si Piezoresistive Behavior to Develop a Three-Dimensional Stress Sensing Rosette
DownloadFall 2013
This work involves the design, microfabrication, calibration, and testing of a new silicon-based piezoresistive rosette capable of extracting the three-dimensional (3D) stresses in the silicon upon deformation. A new 10-element piezoresistive rosette was devised to extract all stress components...

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 MEMS-based Piezoresistive Three Dimensional Stress/Strain Sensor with Temperature Compensation
DownloadSpring 2020
In this research, a developed n-type piezoresistive three dimensional (3D) stress sensor with full temperature compensation is presented. The proposed sensing rosette benefits from the stress insensitivity of the full-circular n-type piezoresistor, oriented over (111) silicon plane, to detect...

Development of an optical biosensor based on Mach-Zehnder Interferometry for detection of Listeria monocytogenes
DownloadFall 2013
Label-free optical biosensors are widely used for the detection of pathogens due to their low-cost, real-time detection and high sensitivity. A Mach-Zehnder Interferometer (MZI) based biosensor has been developed for the detection of gram-positive bacteria, Listeria monocytogenes. An extensive...
