1. A multi-turn coil device comprising:
- a. a flexible circuit board having a first side, and a second side on the opposite side of the flexible circuit board as the first side when the flexible circuit board;
is unfoldedb. a plurality of serially electrically coupled coils coupled to the flexible circuit board, each coil having a coil direction, and wherein the coils are positioned such that each coil substantially overlaps each of the other coils when the flexible circuit board is folded; and
c. one or more conductive paths formed from the first side to the second side of the flexible circuit board, wherein one or more coils of the plurality of serially electrically coupled coils are coupled to the second side, and wherein at least one coil of the plurality of serially electrically coupled coils on the first side is electrically coupled to an opposing coil of the plurality of serially electrically coupled coils on the second side through the one or more conductive paths when the flexible circuit board is unfolded.

Abstract
A multi-turn coil device comprising a flexible circuit board and a plurality of serially electrically coupled coils coupled to both sides of the flexible circuit board. The coils are formed such that when the circuit board is folded in an accordion manner, the coils are substantially aligned and have the same direction of current flow. The coils are serially coupled sequentially from front to back and back to front wherein the coupling of the coils is through a plated through hole in the flexible circuit board.
