For the development of the totally implantable artificial organs, it is an important problem to monitor the conditions of the implantable devices, especially, when used in the clinical cases. In this study, we use the sensors for the 3-dimensional (3-D) virtual reality (VR) system for the monitor of the implantable artificial heart. The position sensors using electro-magnetic forces were attached to the inner actuating part. Sensitivity of the position sensors were the order around 0.8 mm at sampling time is 120 point/sec. By the use of these VR position sensors, we could easily detect the position, movement, and pitch yaw, roll of these sensors. The experimental evaluation using moc circulation loop and healthy adult goats were performed. Experimental results suggest that our newly developed implantable sensors for monitoring the implantable artificial heart system were useful for sensing driving condition suggesting may be useful for the implantable devices for the clinical usage.
