Abstract: Structures, devices, and methods for wireless power transfer systems are described. A structure can include a plurality of strands a plurality arranged into a coil layer. For every fixed interval along a length of the structure, the plurality of strands can be folded at a lateral angle and vertically inverted in response to being folded at the lateral angle. The plurality of strands being folded can cause the plurality of strands to surround a center of the structure in a parallel path.

Abstract: Structures, devices, and methods for wireless power transfer systems are described. A structure can include a plurality of strands arranged into a first coil layer and a second coil layer. The plurality of strands can be formed on a parallel path surrounding a center of the structure. The plurality of strands can extend away from the center on the first coil layer. The plurality of strands can extend towards the center on the second coil layer. For every fixed interval along a length of the structure, a first strand among the plurality of strands can be looped from the first coil layer to the second coil layer and a second strand among the plurality of strands can be looped from the second coil layer to the first coil layer.

Abstract: Apparatuses including a coil and methods of forming the coil are described. The coil can include a first coil layer including at least an inner strand and an outer strand. The coil can further include a second coil layer including at least an inner strand and an outer strand. The inner strand of the first coil layer can be connected to the outer strand of the second coil layer. The outer strand of the first coil layer can be connected to the inner strand of the second coil layer.
