Abstract
Cross coils that operate in an alternating magnetic field are proposed for transmitting signals. They cancel the noise induced by a symmetric magnetic field stem from a transcutaneous power-transmitting coil, and then transmit and detect the signals in the magnetic field. In comparison with figure-of-eight coils, cross coils keep a certain sensitivity due to dislocation between the transmitting and detecting coils. The signal-transmitting ability of cross coils is not very high, but above properties make them useful as transcutaneous signal-transmitting coils.
