Energy Harvesting

Thermoelectric Generators (TEG) generate electricity from any thermal source. If one side of the TEG is warmer, or colder than the other, electricity is generated. TEGs function without toxic substances or moving parts, guaranteeing a long, maintenance free life cycle. Energy Harvesting refers to the process in which small amounts of electricity are generated for applications such as sensors, actuators, consumer electronics and applications in research.

Energy harvesting utilizes existing thermal sources to generate electricity. The thermal difference between the human body and ambient air, or the heat emitted by a central heating tube are typical examples of applicable thermal sources. Possible applications of gTEG®s as Energy Harvesting modules include, but are not restricted to:
