     Transcutaneous energy transfer system (TETS) for ventricular assist device (VAD) is a safe and effective technique that allows power to be delivered to implants wirelessly, avoiding the use of percutaneous wires. TETS is sensitive to mutual electromagnetic interference when multiple TETSs concentrate in the same location which may danger to device wearers. In this paper, two TETSs will be arranged in eight different configuration patterns to verify if it is possibility that mutual electromagnetic interference can enhance biological effects of human body by measured the internal electric fields (EINT) and TETS output voltages (Vout). The operating frequency of TETSs were fixed to 400 kHz. A novel four-layer human body simulation models consist of dry skin, wet skin, fat, and muscle were used as the TETS’s wearers. The results indicated that EINT was increased by 16.4% and Vout was increased by 15.5% in the worst case. To ensure that TETS can be used safely, the distance between wearers should be greater than 20 cm within the simulations.
