C8.1 - Thermo-Electric Energy Harvester for Low-Power Sanitary Applications

C. Beisteiner & B. G. Zagar
The paper presents solutions for self-sufficient energy supply for sanitary applications. The difference in temperature between a hot and cold water pipe is utilized via a thermo-electric generator to feed a DC/DC converter. A sufficiently large voltage can be gained even for moderate temperature differences to power a DC/DC converter capable of stepping-up from low feed voltages in the range of a few millivolts. We could show that even the rather small temperature difference between...
