A Cuttable Wireless Power Transfer Sheet

For fabricating furniture with wireless power transfer (WPT) capabilities, designers need to fix the the appearance/mechanics of the furniture first, and then design the circuitry specialized for each particular case. Moreover, when a wide power transfer area is intended, it is necessary to implement coil arrays, which cause interference between the coils: specialized engineering technique is required to overcome this problem. To enable furniture designers to easily/quickly build furniture with WPT, we propose a cuttable coil array board that can power devices placed on a large area and can be freely cut by furniture designers to modify its size and shape.
