A thermoelectric converter for energy supply

A thermoelectric power generator in silicon technology is used for the energy supply of low power systems. An application is described generating an electrical power of 1.5 μW with a temperature difference of 10°C. With the generated electrical power it is possible to operate a small preamplifier and a sensor control system. For complexer applications a generator with a power in the region of 20 μW would be desirable.
