Abstract
A current sensing system and method for wireless energy transfer may include a printed circuit board, wherein the printed circuit board may include at least a first layer, a second layer, and a third layer. A loop of conductive material may be included, wherein the loop of conductive material may include a diameter D3 on the second layer. A coil of conductive material may be included, wherein the coil of conductive material may have at least 2 turns, wherein a majority of the coil of conductive material may occupy the first layer and the third layer with an outer diameter D1 and an inner diameter D2, connected through each of the first, second, and third layers. The loop of conductive material may be coupled to the coil of conductive material.
