Power and Data Telemetry for Biomimetic Microelectronic Systems
The newly developed systems from NSF BMES ERC will allow bi-directional communication with tissue and by doing so enable implantable/portable microelectronic devices to treat presently incurable diseases such as blindness, paralysis, and certain central nervous system disorders. Our role in the center’s goal is guided by four basic themes and fundamental challenges: power efficiency, bi-directional communication capability, miniaturization, and integration. We are addressing the above challenges through fundamental theory and prototyping of subsystems such as wireless power and data telemetry, microstimulators, neural recording systems, image processing.
