Abstract

A method of detecting a receiver (214) by a transmitter and a transmitter for detecting a receiver are provided. The transmitter is intended to transmit power inductively to the receiver (214). The transmitter comprising a first transmission coil as a first electrode (204) and a second electrode (206). The first electrode (204) and the second electrode (206) form a capacitor (202). The method comprises the steps of applying a voltage (216) to any one of the electrodes (204, 206) and detecting a capacitance change of the capacitor (202).
