Microcantilever sensor has gained much popularity because of its high sensitivity and selectivity. It consists of a micro-sized cantilever that is usually coated on one side with chemical/biological probe agents to generate strong attraction to target molecules. The interactions between the probe...

Resonant microcantilevers are promising transducers for bacteria detection because of their high sensitivities. Surface stress and mass from adsorbates affect the resonant frequency. We developed a novel method for decoupling the frequency contributions of a change in mass and surface stress on a...

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...

Top-Orthogonal-to-Bottom-Electrode Capacitive Micromachined Ultrasound Transducers for Low-Cost 3D Ultrasound Imaging
DownloadFall 2013
Capacitive micromachined ultrasound transducers (CMUTs) offer a promising solution for three-dimensional ultrasound imaging due to their ability to be easily fabricated in two-dimensional arrays. However, channel routing is still non-trivial and cost-intensive. The subject of this thesis is a...
