  • Planar resonator for wireless power transfer
    Patent number: 6960968
    Abstract: A planar resonator and method of manufacture provides contactless power transfer using at least two electrically isolated axis aligned conductive across the transfer interface in a coupled inductor or transformer configuration. Signal or power transfer is then accomplished by coupling of magnetic flux. The coupling of electric flux is also accomplished across a same interface and driven with the same conductive spiral-wound conductors. An interface of energy transfer(IOET) has a first spiral-shaped conductor arranged on the top surface of said IOET; a second spiral-shaped conductor arranged on the bottom surface of said IOET, has a vertical axis aligned with the first spiral-shaped conductor. The IOET and the first and second spiral-shaped conductors have a predetermined self-resonant frequency.
