Abstract:
An out-of-plane coil structure, comprising:a substrate; an elastic member comprising a first anchor portion, a loop winding and a second anchor portion, the first anchor portion and the second anchor portion being fixed to the substrate; wherein the elastic member further comprises a first elastic member comprising a first anchor portion and a first free portion and a second elastic member comprising a second anchor portion and a second free portion; wherein the first free portion and the second free portion are initially fixed to the substrate, but are released from the substrate to become separated from the substrate, and wherein an intrinsic stress profile in the first elastic member biases the first free portion away from the substrate and wherein an intrinsic stress profile in the second elastic member biases the second free portion away from the substrate; and wherein the first free portion and the second free portion are connected together forming the loop winding.
