United States Patent Application

View the Complete Application at the US Patent & Trademark Office
An energy harvester generates electrical energy from mechanical energy using changing flux properties in primary and secondary flux paths. An apparatus includes at least two primary flux paths. The primary flux paths include at least one bias flux path configured to exhibit a change in a flux property in response to a change in an external load applied to the bias flux path. The secondary flux path is magnetically coupled to the primary flux paths. The secondary flux path is configured to experience alternating flux directions in response to the change in the flux property of the bias flux path. Electrical energy can be induced in a conductor as a result of the alternating flux direction in the secondary flux path.
