Future Medical Wearables Could Be Powered By Body Heat, North Carolina State University Study

Researchers at NC State think that they have developed a new way to harvest body heat and turn it into electricity. The team has developed a patch that’s roughly a centimeter squared, that would attach to a person’s bicep. The device would then be able to generate anything up to 20 Microwatts, a significant increase on previous technologies. It’s not enough to power a smartwatch, but it’s possible that it may be enough to juice a medical sensor, reducing the number of bulky cables a patient has to trail around them.
