Abstract

Active medical implants are implantable devices that require a source of energy to perform their function. To ensure energy supply to these devices, in order to reduce mobility and infection problems due to power cables passing through the patients' skin, the Transcutaneous Energy Transmission (TET) system is proposed. These devices use time-varying electromagnetic fields, constituting a wireless power transmission system. Due to the phenomena involved in this transmission, considerations about biological tissue heating and electromagnetic compatibility behavior of the system are necessary. For this, one can make use of computer programs of electromagnetic simulation and bench measurements. Bench tests can be supported by the use of additive (3d-print) manufacturing of anatomical structures, which also allow a study of the positioning of couplers for energy transmission. As a result, the development of national technology and a product that can lead to an increase in the quality of life of implanted patients and reduction of postoperative costs with treatments of possible infections are expected.
