Abstract :
In implantable medical devices such as artificial hearts, it is important to communicate device control and monitoring signals across the skin for its stable operation. Using the signal transmission coil pairs we have proposed, we studied through measurements and experiments the best carrier frequency, based on the frequency characteristics of the L/C resonance circuit that inherits in the coil geometry.
