Summary
A transcutaneous energy transmission system (TETS) was composed of a couple of coils, which formed a transformer across the skin, a driving circuit, and a rectifying circuit. By using coreless coils and a high driving frequency (100–160 kHz), more than 25 W of electric power could be transmitted with 78.5% of maximum efficiency (dc to dc). In animal experiments, the primary coil temperature during operation was under 39°C on thermograms. After 10 months of implantation of a secondary coil coated with epoxy resin, it was wrapped by a thin capsule of connecting tissue. No obvious tissue reaction was recognized.
