We have been studying the transcutaneous communication system(TCS) using the intra-body communication, and we developed the implantable miniature TCS in which a Lithium battery was integrated on a circuit board. We examined the implantable TCS in the animal experiment, and the implanted TCS inside the goat’ thoracic cavity was not able to communication with the external unit at all. From the in vitro experiment for verification of the animal experiment showed that the amplitude of the receiving signal on the receiver is proposal to the distance between the battery and the circuit board on the transmitter, and integration of the battery on the transmitter circuit board is difficult to achieve data communication. From the results, we develop a new implantable miniature TCS unit in which the battery is separated from a circuit board. In addition, the receiver circuit is redesigned in order to improve receiving sensitivity.
