A thermoelectric generator (TG) directly embedded in aluminum is described. The device has been realized using a new silicon thermocouple process with very high temperature stability. It is integrated by direct embedding in the liquid aluminum during casting. The TG generates up to 500 μW of external electric power. The new technology also opens the path to a new generation of sensors and microsystems embedded in metals during primary shaping.
