WIRELESS ELECTROMAGNETIC RECEIVER AND SYSTEM OF WIRELESS ENERGY TRANSFER Russian patent published in 2013 - IPC H02J17/00 

FIELD: electricity.

SUBSTANCE: system of wireless energy transfer is proposed, which comprises a source of an AC magnetic field and a wireless electromagnetic receiver, which receives energy from a source of an AC magnetic field. The receiver comprises a device sensitive to electromagnetic field, and a device made as capable of conversion of mechanical energy into electric one, differing by the fact that the device sensitive to electromagnetic field in the receiver is an integral solid-state mechanical resonator, made of a magnetostrictive material, and the second device represents an inductive converter of mechanical energy of specified resonator oscillations into electric energy, besides, such converter does not contact mechanically with the resonator.

EFFECT: increased received power by increase of receiver's good quality.
