Transcutaneous energy transfer system (TETS) is one of the methods to supply electric power to an assisted heart. In this study, we analyzed the effects of electric fields in the body on biological tissues around the TETS. Using an electromagnetic field simulator, biological tissue models consisting of Dry-Skin, Wet-Skin, Fat, and Muscle were fabricated. When the frequency was fixed at 400 kHz and the transmission distance at 20 mm, the analysis was conducted by changing the transmitting coils from 2 to 4 layers and the receiving coils from 1 to 4 layers in order to suppress the electric field strength inside the body. The results showed that the lowest internal electric field was observed at 2 layers of transmitting and 4 layers of receiving coils, and the maximum internal electric field was 77.07 V/m. This result was below the occupational of the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guideline.
