Abstract

A temperature and output power control transformer that is applied to an implanted device called artificial sphincter that is composed of shape memory alloy (SMA) is examined. The artificial sphincter is using phase transformation of SMA depending on temperature. To prevent overheating, we examined temperature control utilizing thermosensitive magnetic ferrite. As the temperature rises, the power decreases that is conveyed through the transformer that uses thermosensitive ferrite as its core. If the heater attached to SMA is provided with the electric power through the transformer, it is possible to control the temperature of SMA.
