Abstract
Wireless power transfer with inductively coupled coils is widely used for powering implantable devices. For a continuously moving receiver coil (Rx), real-time detection of its position is important for the magnetic field distribution control. This paper proposes an Rx positioning system that uses three varying-pitch coils and applies a trilateration algorithm for positioning. It operates at a frequency of 125 kHz. The detection area is approximately 224 cm2, when using a 2 cm radius Rx. Experimental results show the position detection system has a 1 cm2 resolution with an average deviation of 6.8 mm.
