coil. Signal transmission coil has been designed, allowing for noise disturbing, and reported to have sufficient transmitting ability.

Abstract

For use of implanted apparatus such as an artificial heart, monitoring of driving condition and detection of trouble are necessary. These informations exist in the body and have to be transmitted through the skin. So the transcutaneous signal transmission system without wire penetrating skin is to be considered.
The driving power of the artificial heart is provided from the outside of the body to the inside. One of this method is that a pair of coil is arrraged with the skin in between and this magnetic coupling enables power transmission in contactless condition. In the same way, magnetic coupling method is utilized in signal transmission system and able to transmit the information inside the body to the outside with transcutaneous coil. Signal transmission coil has been designed, allowing for noise disturbing, and reported to have sufficient transmitting ability.
In this report, the multiplexing of the transcutaneous signal transmission system is considered experimentaly. We design the signal transmission coil and decide the signal frequency band based on frequncy characteristics of coil. Moreover 5 channel signal transmissions are practiced in frequency-division multiplex and examined in effect on noise removal and signal separation.
