Body Heat Captured to Power Lightweight Wearables
Publication/Creation DateJanuary 23 2019
DescriptionScientists from the University of Massachusetts have developed a fabric that can harvest body heat to power small wearable devices such as fitness trackers.
Materials chemist Trisha Andrew and her Ph.D. student Linden Allison have developed the fabric that uses the “thermoelectric” effect that occurs when there is a difference between body temperature and ambient cooler air.
The fabric has a high electrical conductivity and a low thermal conductivity which enables it to move electrical charges from a warm region toward a cooler one using this effect while many scientists have identified the heat from a human body as a possible source of power for wearables.
