Wearable medical devices offer a convenient means of monitoring many physiological features of our body. These devices, which include insulin pumps, continuous heart rate monitors, and neural stimulators, need an electric power source to function. Now, a team of scientists at Purdue University has developed self-powered wearable triboelectric nanogenerators (TENGs) with polyvinyl alcohol (PVA)-based contact […]
