Micropelt Energy Harvesting
Thermoelectric (TE) energy harvesting is based on the heat flux through a thermoelectric element or a thermogenerator comprising a multitude of such elements. The heat flux is driven by a temperature difference across the element. The generated voltage is proportional to the number of elements and the temperature difference. Micropelt thermogenerators contain hundreds of such elements, also referred to as leg pairs – 10 to 100 times more than conventional TE devices. Hence our thermogenerators produce voltages in the range of 0.5 – 5 Volt depending on actual temperature differences on some 12 square millimeters of footprint – sufficient energy to drive a wide range of low-power wireless applications including remote sensors, data loggers and small actuators. Micropelt » chip-thermogenerators support easy physical integration in all kinds of mechanical custom designs for self-sufficient heat-exposed applications.
