Abstract
A temperature sensor includes a semiconductor wafer ( ) with a recess wherein is placed a sensitive element ( ) which is heated in response to a target infrared radiation, and thermal insulating layer ( ) provided between the sensitive element ( ) and the wafer ( ), a thermoelectric element ( ) which generates a first electric signal (V ) representing the difference between the target temperature and a reference temperature, and a device sensing temperature by contact ( ), transmitting a second signal (V ) representing the reference temperature. The sensor includes an electronic device for processing the signals (V , V ) transmitted by the thermoelectric element ( ) and the device sensing temperature by contact ( ), this device consisting of component formed in the semiconductor wafer ( ).
