International audienceThe use of artificial organs completely implanted in the body of the patient requires a design of Transcutaneous Energy Transmitters (TET) that provide more comfort and reliability to the patient, i.e., a TET as small as possible with the least increase of temperature and that meets several project requirements. In this paper, the multi-objective genetic algorithm (MGA) optimization method is used to minimize volume and dissipated power per coil area of round spiral TETs. It assures the transmission of 13 W of power and load voltage within limits defined by the electronic circuits at coil gaps up to 25 mm. A variable resistance that absorbs a defined active power is used instead a fixed resistor load in order to best represent the artificial organ with regulator. Moreover, the paper discusses model issues such as the influence of the misalignment between the coils on the coupling of the TET
