 A transcutaneous energy transmitting system (TETS) enables wireless non-penetrating power supply to ventricular assist device. Design of a transcutaneous transformer embedded in a biological tissue has not been studied. Conduction and displacement currents flowing between transmitting and receiving coils may increase in simulated biological tissue as compared to when a TETS’ transformer is placed in air. Therefore energy transmission efficiency is decreased. In this study, we focused on the impedance between transmitting and receiving coils and proposed an equivalent circuit in simulated biological tissue. To evaluate the validity of the proposed equivalent circuit, we compared the transmission efficiency of the measured values with the values derived from the proposed equivalent circuit. Using the proposed equivalent circuit, these values are in good agreement below 2 MHz. It is confirmed that our proposed equivalent circuit is useful to design a transcutaneous transformer embedded in a biological tissue.
