Micropelt Power Generation

Thermoelectric power generation is based on a heat flux through a thermoelectric element or a thermogenerator. The heat flux is driven by a temperature difference across the element. The generated voltage is determined by pairs of inversely doped semiconductor blocks, called leg pairs. Micropelt thermogenerators contain hundreds of such leg pairs – ten to hundred times more than conventional devices. Hence our thermogenerators produce voltages in the range of 0.5-5 Volt depending on actual temperature differences on just a few square millimeters of footprint – sufficient for driving a wide range of low power wireless systems such as remote sensors or self-sustained data loggers.
