Abstract
A tile is provided with built in wireless power transfer technology that enables power to be wirelessly transferred from a wireless power transfer resonator of the tile to a wireless power receiver device of the tile. The wireless power receiver device includes, or is electrically coupled to, one or more electrical devices disposed on a front surface of the tile that are to be power by the receiver device. An array of the tiles may be provided in which case each tile has a wireless power transfer resonator. At least one of the tiles of the array is electrically coupled to an RF power source. The EM field generated by each tile is inductively coupled from that tile to a nearest-neighbor tile of the array.
