Abstract
Department of Biosignal Processing, Ilmenau University of Technology, Ilmenau, Germany,johannes.miersch@tu-ilmenau.deAbstract— In modern medicine, monitoring de-vices for mobile application are using rechargeablepower supplies. A new concept refers to energy scav-enging techniques using heat emission from humanbody. This project deals with the development of aprototype and the feasibility study of a thermal har-vester.A thermoelectric generator enables the device towork self-sufficient on temperature gradients be-tween skin and ambient conditions. This developedenergy harvesting system converts human body heatinto electrical energy. In combination with ultra-low-power components autonomous operation should bepossible. The system should enable an R-wave de-tection circuitry. If the temperature gradient is highenough, there is supposed to be no lack of power as incase of ordinary battery systems.A system combining thermal energy harvestingand signal processing is developed. To show the func-tions of the energy harvester corresponding measure-ments are performed. The signal processing unit is setup but not evaluated in concrete measurements.Keywords— Thermal Energy Harvesting, R-Wave-Detection, Thermoelectric Generator, TEG
