This report covers a transduction scheme using surface micromachined tuning forks to measure small forces. This resonant sensing is done by applying an axial force to the tuning fork and measuring the resulting shift in natural frequency. The analysis of the tuning forks is carried ...

In this work, design of capacitive accelerometers with CMOS electronics is investigated. The goal of this investigation is to form accurate behavioral models at three different levels of abstraction: system, electrical, and mechanical. Analysis of these models permits a deeper understanding of both accelerometer design and design trade-offs. The results of this work are used to obtain an accurate prediction of accelerometer performance. At the system level, simultaneous force-balancing and analog-to-digital...

The present work aims to provide new tools for the manipulation and detection of biological samples. They can be envisioned as individual components of an integrated, lab-on-a-chip system. A novel SU-8 microgripper is introduced for the manipulation of single cells or other biological species in solution with minimal undesired interactions. The electrothermally activated polymer gripper consists of two SU-8 ‘hot-and-cold-arm’ actuators that are fabricated in a two-mask...

1997
The need for inexpensive yet reliable angular rate senors in fields ranging from automotive to consumer electronics has motivated prolific micromachined rate gyroscope research. The vast majority of research has focused on single input axis rate gyroscopes based upon either translational resonance, such as tuning forks, or...

The goal of this research is the creation of robust, flexible, polymer sensors and circuits fabricated partially from the low cost biopolymer, chitosan, the deacetylated form of chitin which is the second most abundant polyssacharide in nature. Chitin is found in crustaceans, insects, bacteria and fungi. The sensors will detect diatomic gases and DNA to more complex macro molecules (e.g. exotoxins) in a fluidic or dry environment. Polymer-nanoparticle (e.g. Ge) hybrid films allow for development of robust polymer thin-film transistors and, with optimization of the hybrid film,...

2006
Since the beginning of civilization, there has been a thrust to better ourselves, to enhance our performance and capabilities. With nature as a template, a variety of sensors were created. As technology improved, artificial sensors have mostly surpassed their natural counterparts in sensitivity and size except in several specific areas, one being infrared sensing. The Melanophila acuminata, also known as the jewel beetle, is one of ...
