Power/Performance Bits: Feb. 11

By Jesse Allen - 11 Feb, 2019 - Comments: 0

Body heat harvesting Chemists at the University of Massachusetts Amherst developed a fabric that can harvest body heat to power small wearable electronics such as activity trackers. The device works on the thermoelectric effect created by body temperature and ambient cooler air. "What we have developed is a way to inexpensively vapor-print biocompatible, flexible and lightweight polymer fil... » read more
