MIT and Texas Instruments researchers have unveiled a new chip design for portable electronics that can be up to 10 times more energy-efficient than present technology.

The design could lead to cell phones, implantable medical devices and sensors that last far longer when running from a battery.

One future goal for implantable medical devices is to make the power requirements so low that they could be powered by “ambient energy”–using the body’s own heat or movement to provide all power.
