The discoveries culminate years of efforts by
The technology could provide a path toward a new type of medicine that allows physicians to treat diseases with electronics rather than drugs.
"We need to make these devices as small as possible to more easily implant them deep in the body and create new ways to treat illness and alleviate pain," Poon said.
The article describes how Poon's team built an electronic device smaller than a grain of rice that acts as a pacemaker. It can be powered or recharged wirelessly by holding a power source about the size of a credit card above the device, outside of the body.
The central discovery is an engineering breakthrough that creates a new type of wireless power transfer that can safely penetrate deep inside the body, using roughly the same power as a cell phone.
The research is published in the Proceedings of the
