Engineering Minute – Wearable Device Harvests Energy From Walking

A research team from Penn State Materials Research Institute and University of Utah has developed a wearable device that harvests energy as a person swings their arm while walking or jogging. Using specialized piezoelectric materials and magnets the wristwatch-like device is able to produce enough energy to power a personal health monitoring device. The hope is that the device will be able to power internet-of-things devices and reduce battery waste.
