Materials Science and Engineering students at the A. James Clark School of Engineering, University of Maryland take a capstone design course in their senior year. In recent years, they have worked projects including a shape memory alloy, self-healing polymers, carbon nanotubes for organic solar cells, zinc oxide tetrapods for microelectronic sensors--all with interesting potential real-world applications. The graduating class of Spring 2010 made this video to document the stages of development of their project.
These seniors designed a tiny dynamic microelectromechanical systems (MEMS) microphone for use in products like phones, laptops, and hearing aids that does not require a power source for signal generation. The use of electromagnetic induction to translate sound to an electrical signal has been used in macro-scale devices, but has not been created for commercial use at the micro-scale.
