Abstract

The present disclosure relates to a thermal sensor and a method for producing a thermal sensor of this type having a low signal-to-noise ratio at relatively high signal strengths. To this end, a thermoelectric generator is combined with a field effect transistor and a diode. Owing to its integrated diode and the barrier effect associated therewith, the thermal sensor is suitable for the economical and efficient design of imaging sensor arrays for converting thermal radiation into electrical signals.
