Abstract
Wireless power transfer system include: a seat configured to support a human and including a first resonator featuring a conductive coil formed by a plurality of loops that each encircle a common first axis, a layer of magnetic material, and a conductive shield; an article of clothing featuring a second resonator having a conductive coil formed by a plurality of loops that each encircle a common second axis, so that when the article of clothing is worn by the human and the human is seated in the seat, the first and second axes are aligned; and a first electronic apparatus positioned in the seat and coupled to the first resonator, and configured to deliver electrical power to the first resonator so that during operation of the system, power is transferred wirelessly from the first resonator to the second resonator.
