Energy Harvesting for Biomedical Devices & Health Care Intelligent Infrastructure

The project goal is to develop an integrated reliable and biocompatible power supply which harvests energy from body movement, temperature, or external light.  Such a power supply would extend the lifetime and functionality of implants and enable a new generation of biomedical devices for smart health care.  The project was seed funded by CITRIS.  The research has resulted in advancements in key components of an energy harvesting system, including: development of a piezo disk energy harvester; construction of an energy-aware multi-input power IC; and demonstration of the feasibility of thermal energy generation in the body.  Work on this project continues with funding from the Bosch Research and Technology Center; additional funding is being sought from NSF as part of a larger application.
