The use of artificial organs completely implanted in the patient's body requires a transcutaneous energy transmitter (TET) design that provides 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. The multiobjective genetic algorithm optimization method is used here to minimize volume and dissipated power per coil area of round spiral TETs. It ensures the transmission of 13 W of power and load voltage within limits defined by electronic circuits at coil gaps of up to 25 mm. A variable resistance that absorbs a defined active power is used instead of a fixed resistor load to best represent the artificial organ with regulator. Modeling issues, such as the influence of the misalignment between the coils on the coupling of the TET, are also discussed. (AU)
