ABSTRACT:
An energy harvesting apparatus and method. In one form the apparatus makes use of a pair of flexible beams that are supported at first ends thereof from a base. Second ends of each of the beams are operatively coupled to rigid links. The rigid links are in turn operatively coupled to a mass component that is free to move linearly in a path generally parallel to the longitudinal axes of the flexible beams. Movement of the mass component in response to vibration forces causes a twisting moment to be applied at the second end of each flexible beam. This causes a uniform flexing of each of the flexible beams. A piezoceramic material layer on each beam generates electrical signals in response to the flexing motion of the beam.
