This work describes the development of both miniature-scale and micro-scale rotary internal combustion engines. This work is part of a project to develop a portable, high specific energy, liquid hydrocarbon-fueled power supply. A Wankel-type rotary engine was chosen for development because of its self-valving operation, planar geometry, and the ability to extract either mechanical or electrical power. To investigate engine behavior and design issues, larger-scale "mini-rotary'' engines have been fabricated from 4 steel. Mini-rotary engine chambers are approximately 1000 mm3 to 1 700 mm3 in...

The increasing demands for higher performance, advanced wireless and mobile communication systems have continuously driven device innovations and system improvements. In order to reduce power consumption and integration complexity, radio frequency (RF) microelectromechanical systems (MEMS) resonators and filters have been considered as direct replacements for off-chip passive components. In this dissertation, a new radio architecture for direct channel selection is explored. The primary elements in this new architecture include a multitude of closely-spaced narrowband filters (...

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,...

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 ...
