1. An apparatus for power transfer over air, comprising:
a conductor, printed on a substrate housed in an enclosure, that generates alternating current caused by a magnetic field emitted by a transmitter, wherein the conductor is a trace spanning layers and the trace is perpendicular with the substrate, and a surface area and a width of the trace equal turns for a wire coil, and the trace has subtraces forming a staggered pattern within one of the layers and forms the staggered pattern between at least two of the layers; and
a rectifier, on a device housed in the enclosure, that receives the alternating current through a terminal connected with the conductor and converts the alternating current to a direct current for powering a load, wherein an insulator between the conductor and the rectifier isolates the magnetic field.
