Charge Your Smartphone While You Walk
New technology allows your steps to create an electrical current that could be used to power your mobile devices.
A small device placed in your shoe could generate enough wattage to power your cellphone with every step you take. The device is created by engineers Tom Krupenkin and Ashley Taylor from the University of Wisconsin. The technology efficiently harnesses kinetic energy and turns it into electrical current using Galinstan, a liquid metal alloy that is often used in thermometers. A press release explains:
Two small pouches are filled with a fluid that is designed using nanotechnology to generate an electrical current when compressed over and over again by the up and down motion of the foot.
