Wireless System Paves Way for 'Electroceutical' Medical Devices

A wireless system uses the same power as a cell phone to safely transmit energy to chips the size of a grain of rice. The technology paves the way for new "electroceutical" devices to treat illness or alleviate pain.

The central discovery is an engineering breakthrough that creates a new type of wireless power transfer that can safely penetrate deep inside the body.

The technology could spawn a new generation of programmable microimplants – sensors to monitor vital functions deep inside the body; electrostimulators to change neural signals in the brain; and drug delivery systems to apply medicines directly to affected areas.
