    Abstract: A film structural component is supported by a substrate. The film structural component includes a plurality of thermal infrared detectors arranged in an array. Each of the plurality of thermal infrared detectors includes a thermopile having a plurality of hot junctions and a plurality of cold junctions. An infrared sensor further includes a plurality of heaters and at least one thermometer. The plurality of heaters are provided on the first principal surface of the substrate. The at least one thermometer is provided on the first principal surface of the substrate and is configured to detect a temperature of the substrate. Each of the plurality of heaters faces another heater of the plurality of heaters via a region including the plurality of thermal infrared detectors in plan view in the thickness direction of the substrate.

    Abstract: A sensor system includes a sensor element, a signal processing circuit, and a pseudo-signal correction circuit. The sensor element outputs an electric signal corresponding to an external force. The signal processing circuit converts the electric signal coming from the sensor element into a signal having a certain signal format and then outputs the signal thus converted. The pseudo-signal correction circuit corrects a pseudo-signal outputted by the sensor element. When receiving a test signal, the sensor element performs a self-diagnosis based on the test signal and then outputs the pseudo-signal, which represents a result of the self-diagnosis. The pseudo-signal correction circuit corrects the pseudo-signal based on environment information about an environment where at least one of the sensor element or the signal processing circuit is located.
