EMBEDDED MAGNETIC FIELD INDICATOR ARRAY FOR DISPLAY OF UNIFORMITY OR BOUNDARY OF MAGNETIC FIELD

摘要

Methods and apparatus relating to embedded magnetic field indicator array for display of uniformity or boundary of magnetic field are described. In an embodiment, a diode is coupled to a coil in series. The coil receives wireless energy from a wireless power transmitter and generates an electrical current in response to the receipt of the wireless energy to cause the diode to emit light. The coil is to be formed by at least two coil loops (which may be spiral or overlapping). Other embodiments are also disclosed and claimed.
