A new way to beam power to medical chips deep inside the body

A Stanford electrical engineer has invented a way to wirelessly transfer power deep inside the body, and use this power to run tiny electronic medical gadgets such as pacemakers, nerve stimulators, or new sensors and devices yet to be developed.

The discoveries reported Monday May 19 in the Proceedings of the National Academy of Sciences (PNAS) culminate years of efforts by Ada Poon, an assistant professor of electrical engineering, to eliminate the bulky batteries and clumsy recharging systems that prevent medical devices from being more widely used.
