Magnesium silicide TEGs as self-sufficient power supply for smart systems

Thermoelectric generators (TEGs) can be used as a self-sufficient power supply. Thereby, the application in smart systems is promising because of the large number of sensors which often also have a low power consumption. To ensure cost effective TEGs a mass producible cold pressed process was developed for Mg2Si. By adapting the process set-up, the sintering temperature and the process atmosphere, densities of spark plasma sintering materials were almost reached.
