摘要：

Artificial organs using shape memory alloy (SMA) fibers have possibilities to achieve small size and simple control. However, there is a problem of the instant heavy load; in this paper we propose an efficient transcutaneous energy transmission system for SMA fibered devices. In this system, the internal storage capacitor is charged slowly while the fibers are turned off and discharge the energy when the fibers are turned on. We examined the effect of the system. Firstly we changed capacitance from 500uF to 34100uF. Secondly we changed input current limitation. There is possibility that the size and maximum output of the TETS would able to be reduced with the internal energy storage system. © 2014, Japan Soc. of Med. Electronics and Biol. Engineering.
