Researchers at MIT and Texas Instruments have designed a new chip that they claim could be up to 10 times more energy-efficient than the current generation. The power consumption in the new chip is so low that devices using them may even be able to be recharged by human body heat. The MIT researchers claim in a university report that implantable medical devices such as pacemakers and health monitors using the new chip could be powered indefinitely by a person's body heat or motion without the need for a battery.
