Abstract:
1. A device comprising: a contiguous flexible substrate; N coiled conductors deposited on the flexible substrate, the N coiled conductors connected in series by conductive interconnects, wherein the N coiled conductors only cover a portion of the flexible substrate, wherein a remaining portion of the flexible substrate represents an insulating flap that does not include a deposited one of the N coiled conductors, wherein the insulating flap has a profile large enough to cover one of the N coiled conductors; and a plurality of folding regions in the flexible substrate, each of the folding regions defined by a separation distance between adjacent ones of the N coiled conductors except that at least one folding region in the plurality of folding regions is between the insulating flap and an adjacent one of the N coiled conductors, wherein the conductive interconnects traverse the folding regions between the N coiled conductors to connect the N coiled conductors in series, wherein the flexible substrate is folded such that the N coiled conductors form a stack of N coiled conductors, wherein the flexible substrate is folded such that the insulating flap is sandwiched between two of the N coiled conductors thereby electrically insulating the two of the N coiled conductors from one another, and wherein N is greater than 1, wherein the conductive interconnects are deposited on the flexible substrate such that at least one of the conductive interconnects is located at the inside of a bend radius created when the flexible substrate is folded.
