Summary:The direction of the designing and improving of the biomedical devices is actively developing. The transcutaneous energy transfer systems are of particular interest. An essential feature of the transcutaneous energy transfer system operating is the heating of biological tissues that caused by power losses on active elements of the device. In this article, the mathematical modelling of the biological tissues heating by the wireless energy transfer system that delivering the power of 500 mW to implant was performed. The dissipated power on active elements of the device was 232 mW. An influence of the personal characteristics of the patient on the temperature distribution was investigated. Mathematical modelling of the heating by the numerical solution of Pennes equation using software COMSOL Multiphysics was performed. The temperature increase is 1.47, 1.88 and 2.03 °C (coaxial layout) and 1.7, 1.94 and 1.98 °C (planar layout) for fat layer thicknesses 12, 18 and 33 mm respectively.
