Wireless power transfer system and method

Abstract:

A wireless power transfer system comprising a transmitter and a receiver. The transmitter arranged to generate a varying electric field, and the receiver located in the varying electric field. The receiver comprising a first element and a second element. The first element and the second element having different geometries so different charge densities are induced on the first element and the second element by the varying electric field such that, in use, a current flows between the first element and second element, through a load connected between the first element and second element.
