Foot pounds of energy?
Researchers at Georgia Institute of Technology have devised a self charging battery unit. By incorporating a piezoelectric material within a Li-ion battery, this generates a charge under mechanical stress and produces a self-charging device. Putting the device on the bottom of a shoe provided a simple route for supplying the mechanical energy for conversion and storage.
