Georgia Tech develops a coin sized battery that charges when you move

When we first heard about a self-charging battery, a mere thought gave us dreams about its existence. Could it be a possibility? Yes, Georgia Tech has come up with a coin sized battery that can fit inside your shoe and recharges itself when you move. The battery is lithium-ion in which electrodes have been swapped with polyvinylidene difluoride film that is covered with piezoelectrics. The researchers have tested the battery and results came out to be positive. All energy that the cell develops is by the movement only, no external voltage is used.
