Abstract: Monitoring of bodily functions in sports has become increasingly popular in recent years. The devices used today are battery-powered, such as sports wristbands. The presented project investigates different approaches for energy harvesting in sportswear. In cooperation with the company Mammut Sports Group AG, a shirt was modified as an experimental wearer in such a way that the thermal waste heat of the body is used to operate a sensor system. In addition to technical feasibility, great importance was attached to wearing comfort. The project showed following results: - The best energy harvesting source of a human body is thermal heat - Energy balance is good - Wearing comfort needs to be improved This project uses thermoelectrical generators (TEG) as a harvesting source in shirts from Mammut Sports Group AG. The temperature difference across the TEGs is defined by the body heat and the ambient temperature. The harvesters are sewed into the shirt using pieces of textiles. Since the output power is highly dependent on the position and the movement of the athlete, a TEG system is developed, where several TEGs are connected serial and parallel. This enhances the power output and increases the robustness against movements or other impacts.
