Abstract
An energy harvester having a plurality of bimorph beams and a plurality of piezoelectric devices, wherein at least two of the piezoelectric devices are mounted to each of the plurality of bimorph beams. A plurality of rigid beams interconnect adjacent ends of the bimorph beams to define a stacked, fan-folded shape having a first end of one of the bimorph beams mounted to a structure. A tip mass is disposed on a free end of another of the plurality of bimorph beams. Upon movement of the energy harvester, the plurality of bimorph beams is caused to deflect and thereby output electrical power from the plurality of piezoelectric devices.
