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. The planar power resonator stores electric energy in the IOET, and at predetermined frequencies, the arrangement of the first and second spiral-shaped conductors and the IOET permits transfers of magnetic flux and electrical energy between the first and second spirals across the IOET. The resonator facilitates contactless battery charging in devices such as cellphones and wearable electronics where the resonator can be woven into fabric or attached to a person's clothes.
