Thermoelectric generator design based on power from body heat for biomedical autonomous devices

Energy harvesting from human body has been undergoing an interesting and quick development thanks to the technological availability of new electronic components and the growing of different applications, in particular, for biomedical and social impacts on human beings´ daily life. The main scope of this paper is to modeling and to design a thermoelectric generator that extracts energy from human tissue warmth in order to supply a biomedical hearing prosthesis for deaf persons. An array of sensors based on thermocouple effect has been used. A conditioning and accumulator circuitry has been designed and tested.
