Abstract :
A flexible transcutaneous transformer utilizing amorphous magnetic fiber for an artificial heart system is reported. The transformer can transmit electrical energy of 20 W with an efficiency of over 90%; the primary current density does not greatly depend on the relative displacement of the coils. The temperature rise of the transformer was about 6°C in a phantom test
