Fraunhofer Energy AllianceMicro Energy Harvesting is a relatively young discipline in the field of mobile power supply of small devices and in off-grid applications. Especially thermoelectric and piezoelectric energy conversion methods are applied here. In thermoelectric energy conversion, a temperature gradient is converted into electrical energy.
Piezoelectric energy conversion is based on the generation of voltage by pressure and vibrations. When monitoring the function in moving or remote plants, systems designed by the Fraunhofer Energy Alliance can provide power for the radio transmission of sensor signals.
