Abstract

An article of footwear having a piezoelectric energy harvesting apparatus in the sole member. Walking or running applies a first force deforming a piezoelectric actuator, thereby generating electrical energy. An energy storage circuit stores electrical energy generated by the piezoelectric actuator for later application to electrical devices.
