A novel wireless charging system for movable telephone with printed-circuit-board windings of different structure and shape respectively

In this paper, a new wireless charging system for movable telephone is addressed. A pair of contiguous printed-circuit-board windings has different shape and structure respectively, which is adopted as a wireless energy transfer device. The structure and principle of wireless charging system are expounded. The novel concept comes into being the basis for a new generation of universal charging system for a wide range of movable telephones. Multifarious movable telephones can be charged simultaneously through the presented charging system, despite their orientations and positions. Furthermore, the feasibility of this system has been demonstrated with the practical measurements. These results provide a useful example for a practical charging system for movable telephone.
