RESONANT WIRELESS POWER TRANSFER CHARGING PAD FOR UNPLANAR DEVICES

A wireless charging device may include a first transmit coil disposed on a first layer, and a second transmit coil disposed on a second layer. The second transmit coil is electrically coupled to the first transmit coil. The first and second transmit coils form a transmit inductor to inductively transfer a wireless power signal. A wireless device capable of being powered by the wireless charging device may include a device housing including a first surface and a second surface. A first receive coil may extend in a first plane in alignment with the first surface. A second receive coil may be spaced apart from the first receive coil, and the second receive coil may extend in the first plane or a second plane different from the first plane and be aligned with the second surface, where the first and second coils inductively receive wireless power signals.
