Transcutaneous Signal-Transmission System Using Cross Coils

Abstract

A transcutaneous signal-transmission system is discussed. We propose the use of cross coils as signal-transmitting coils. A pair of cross coils is placed between power-transmitting pancake coils that transmit power from outside the body to implantable devices, such as ventricular assist devices. Cross coils can cancel the effect of the power-transmitting magnetic fields and transmit signals at the same time. By examining actual-signal transmission, we were able to draw up a guideline on the design of cross coils.
