Can't get your smartphone battery to last through the day? Worried your phone may lose power while you're away from an outlet? Dr. Zhong Lin Wang, Regents' Professor and Hightower Chair in Materials Science and Engineering at Georgia Tech, talks about his work to keep the juice flowing using body movement in today's Wall Street Journal.
Zhong Lin Wang, a professor at the Georgia Institute of Technology, is tackling a new kind of power suit—made from fabric that uses nanotechnology to generate energy as the body moves around.
Any wrinkle in shirts, pants—even undergarments—made with the fabric produces a charge, he says. The trick involves super-slim wires, measuring one-thousandth the width of a strand of hair, that are woven into the fabric. When the specially treated plastic and zinc material moves, it creates mechanical energy that can be harvested by a capacitor, so nobody gets shocked.
