摘要： Systems and methods for a twisted rectangular litz wire for generating or receiving wireless electrical power. The rectangular litz wire may be arranged as a DD coil having first and second co-planar loops. The loops may have a shared single-stacked inner portion and double-stacked outer portions. The litz wire may be twisted between the inner and outer portions, such that a width of the coils at the outer portions is defined by a first longer side of the wires, and a width of the coils at the inner portion is defined by a second shorter side of the wires. This arrangement may reduce a size of the DD coil may reducing a width of the shared inner portion.

The apparatus includes a sense coil formed from a conductor having a predetermined shape configured to attenuate currents induced in the conductor by an external time-varying magnetic field. The sense coil has an electrical characteristic that varies as a function of the presence of the object. The apparatus comprises a detection circuit coupled to the sense coil and configured to detect the presence of the object in response to detecting a difference between a measured value of the electrical characteristic and a reference value for the electrical characteristic. The reference value for the electrical characteristic is substantially the same as the measured value of the electrical characteristic in the absence of the object over at least a portion of the sense coil.
