Spring 2014
Energy harvesting is an important developing field in Microelectromechanical Systems (MEMS) research. In this thesis, a fixed-fixed folded spring-based harvester is presented as an alternative mechanical element for beam-based piezoelectric harvesters to reduce its natural frequency for low...

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...

Spring 2013
Adsorption behavior of nitrogen, argon and oxygen on silver exchanged titanosilicate (Ag-ETS-10) were studied in this work. A low temperature gas chromatographic determination of relatively low concentration argon (<1%) was developed, which was applied to evaluate the production of argon free...

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...

Fall 2022
This thesis lays out the work required to design and create a platform for cryogenically compatible testing of on-chip microwave resonators, intended as a platform for quantum-limited electromechanical torque sensing. We have created a platform with less than 8 dB loss across an operating range...

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...

Fall 2017
Capacitive micromachined ultrasound transducers (CMUTs) are a promising replacement technology for piezoelectric composite transducers, as they offer a more flexible architecture, wider signal bandwidth, and improved impedance matching between the sensor and the sensing medium. While CMUTs have...
