Abstract

We proposed a novel noninvasive power-supply system for medical implants at a deep position in the body. The system consists of the magnetic coupling and the small generator. The former system could keep the power of 1 W supplying until 2.5 cm from the skin and the maximum output power was 3.1 W at 1.5 cm. We have manufactured more powerful generators as the next step. The improvement points are to decrease or eliminate the interference between the magnets at the implanted rotor. As a result, the output power increases 6.6 W and the 1 W supplying distance is extended to 3.0 cm.
