Piezoelectric effect used by US researchers to develop a wearable device that could generate energy from swing of an arm while walking or jogging

The US researchers have developed a wearable device that could generate energy from the swing of an arm while walking or jogging. The device, about the size of a wristwatch, produces enough power to run a personal health monitoring system. The prototype watch is apparently made from a crystal material, which can produce an electric ..
