Abstract
In order to avoid infections caused by a percutaneous power supply cable for an implantable artificial heart, we propose a wireless power transmission system utilizing a magnetic resonant coupling technology, which can transmit electric power with wider gap than that in an electromagnetic induction technology. In order to compensate for decreasing the transmission efficiency due to the relative movement between a transmission coil and a receiver coil, coupling coefficient between the coils is enhanced by controlling attitude of the transmission coil according to the position and attitude of the receiver coil. In this study, effect of enhancing the transmission efficiency owing to both controlling the attitude of the transmission coil and matching the impedance was evaluated. Moreover, a motion capture Kinect is used for measuring the position and attitude of a patient implanting the receiver coil. The measurement accuracy of the Kinect was evaluated.
