Abstract :
This paper proposes an innovative electric power supply system for medical devices implanted deeply, using a low-frequency magnetic field. It is composed of a permanent-magnet coupling and a small generator. The system provides sufficient power at deep positions, adopting two kinds of acceleration. A prototype experiment is carried out and it is verified that the system is able to provide power at deep positions in the human body.
