Abstract

System and methods for wireless energy and data transmission are described. One aspect includes an emitter and receiver. The emitter may include primary and secondary emitting windings. The receiver may include primary and secondary receiver windings. In further aspects, the emitter may include a tertiary emitting winding and the receiver may include a tertiary receiver winding. In one aspect, the emitter uses driving circuitry and the receiver uses rectifying circuitry and one or more capacitors. In further aspects, the emitter and receiver are reversible.
