Abstract
An energy scavenging apparatus comprises a frame which can be human-carried or human-borne; plural cantilevered bimorph piezoelectric members connected to the frame to have an essentially parallel orientation, each cantilevered bimorph piezoelectric member comprising a proximal end connected to the frame and a distal end; and, a mass member connected to the distal end of the plural cantilevered bimorph piezoelectric members.
