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...

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,...

Theoretical and Experimental Investigation on the Use of Surface Acoustic Wave Sensors for Evaluating the Adhesion of SU-8 Thin Films
DownloadFall 2015
This research investigates the use of a SU-8/AlN/Si SAW sensor for evaluating the adhesion of SU-8 thin films. A theoretical model is developed to plot the wave dispersion profile for the SU-8/AlN/Si configuration. A spring interface model is utilized to represent the SU-8/AlN interface using a...
