Abstract

An energy harvester and method for electrical energy harvesting from electromagnetic interference, generated by electrical wiring and/or an electrical appliance, by receiving electromagnetic field energy radiated by the electromagnetic interference and converting the electromagnetic field energy to an electrical current for powering an electrical device. The voltage associated with the electrical current may be increased in preparation for powering the electrical device. The electrical current may be stored in preparation for powering the electrical device.

Claims
