ELECTROMAGNETIC ENERGY SCAVENGER BASED ON MOVING PERMANENT MAGNETS

摘要

An electromagnetic energy scavenger (10) for converting kinetic energy into electrical energy comprises at least one permanent magnet (12) and one or more coils (11) lying in a coil plane, the one or more coils being electrically interconnected for delivery of electrical energy. Upon mechanical movement of the energy scavenger (10), the at least one permanent magnet (12) is freely movable relative to the coils (11) in a plane parallel to the coil plane, thus generating an electrical field in at least one coil (11).
