For the development of totally implantable artificial organs, effective monitoring of implantable devices is crucial. In this study, a sensor for a 3-dimensional (3-D) virtual reality (VR) system and micromachine were used to provide such monitoring. The position sensors were attached to the inner actuating parts of the artificial heart system. Using these VR position sensors, we could easily detect the position and movement, and pitch, yaw, and roll. An experimental evaluation was performed using moc circulation loop and healthy adult goats were performed. By the use of chronic animal experiments using healthy adult goats, micro pressure sensors implanted into the cannulae as part of a ventricular assist system were evaluated. The experimental results suggest that our newly developed implantable sensors for monitoring the implantable artificial heart system would be useful for sensing driving condition, and thus for implantable devices for clinical use.
