摘要
An energy harvesting system for harvesting energy in response to application of an external force. The energy harvesting system comprises a beam member having a central member and at least one piezoelectric layer joined to the central member for deflection therewith. The beam member includes opposing first and second ends and is elastically deformable in response to application of the external force. A first mount couples the first end of the beam member and is generally stationary. A second mount couples the second end of the beam member. The second mount and the second end of the beam member are generally moveable in response to application of the external force between a first position and a second position, thereby outputting energy from the at least one piezoelectric layer in response to the movement from the first position to the second position.
