The final goal of this study is to develop a total implantable biosignal monitoring device which monitors biosignals inside body for long time. For such device transcutaneous digital communication and energy transmission is indispensable. This paper describes a noncontact transcutaneous digital communication using Bluetooth and long distance energy transmission system using core coil. We have developed an implantable biosignal monitoring device equipped with an acceleration sensor, an ECG amplifier, a temperature sensor, a flash memory, a Bluetooth module, a transcutaneous energy receiving coil and a lithium ion battery. We performed an implant test using a cow and transcutaneous digital communication at a distance of 2,700 mm and energy transmission at a distance of 150 mm through the skin were confirmed.
