2013 Poster Sessions : An Integrated and Intelligent Locomotive Implant for Biomedical Applications

Student Name : Edward Lee
Advisor : Ada Poon
Research Areas: Information Systems
Future implantable devices capable of in vivo controlled motion can open up many new possibilities for noninvasive and in vivo medical applications. Some applications include diagnostic, therapeutic, and surgical treatments to attain more accurate diagnosis and enhance the success rate of complex procedures. This work aims to develop a robust controller and test the feasibility of different propulsion mechanisms for the next generation wirelessly powered locomotive implant prototype. Preliminary circuit and COMSOL simulations reveal many engineering obstacles that need to be addressed. Some of these are the sensitivity in received power on the propulsion drive current and the propulsion system itself. Two propulsion techniques are investigated: the asymmetric drag propulsion and piezoelectric-based drive, both requiring significant on-board intelligence for navigation and telemetry.

Edward Lee is a first year doctoral student in Electrical Engineering. During his undergraduate studies at Arizona State University he designed low-noise CMOS imagers on transparent and flexible substrates at the Flexible Display Center. His current research interests include mixed-signal integrated circuits, devices, and optimization theory and implementation for ultra-low power and biomedical applications. He holds the Texas Instruments Stanford Graduate and the NSF Graduate Fellowships.
