This paper presents the development of mechanical SMA urethral valve with transcutaneous energy transformer, which is supplied by batteries. In order to realize the portable type, the constant voltage circuit and the sine wave oscillation circuit are examined through the laboratory tests on cycling characteristics, and so on. From the experimental results, it is seen that the stabilized operation is enabled by introducing the constant voltage circuit between the driving batteries and the other primary circuits, and the efficiency upgrading of electric power transmission was realized by utilizing the sine wave oscillation.
