Examination of circuit parameters for stable high efficiency TETS for artificial hearts

Transcutaneous energy transmission system (TETS) has an advantage that it does not require wires that penetrate the skin to send power inside the body. It prevents the patients from infection-associated syndromes. TETS however, has a difficulty that it has to operate under an unstable coupling factor and varying load resistance. In the worst case, it is known that the heat from the power loss may carry an adverse effect to the body. In this paper, we calculate the circuit parameters that aim for more stable and efficient TETS operations.
