Microchip Powered by Body Heat

Researchers at MIT and Texas Instruments have designed a new chip for portable electronics that could be up to 10 times more energy-efficient than present technology. Given its reduced power consumption, the new chip could lead to mobile phones, handheld computers and remote sensors that last far longer when running from a battery. Indeed, the power required could be so low that implantable medical devices such as pacemakers and health monitors could be powered indefinitely by a person’s body heat or motion — no battery needed
