Abstract
An energy harvester is provided for converting an input force into electrical energy and also allowing for energy to be stored and then released at a later time. The energy harvester includes a receiver, energy collector, converter, and holder, and operates in three stages. The receiver receives the input force and the energy collector is moved by the receiver with an input displacement. The energy collector is then held in a catch position. The input force changes direction, and the energy collector is released by the holder and moves with an output displacement that is different from the input displacement. The converter generates electrical energy from the motion created.
