DIFFERENTIAL TEMPERATURE SENSOR

Sensor including a substrate, an assembly of thermoelectric layers including at least one first and one second junction of a thermocouple, at least one first and one second connection pads arranged to transfer heat respectively to each first and each second junction, a support member (2) of the substrate (3) intended to be connected to the hot source (Sc) and to the cold source (Sf), first and second metal connectors arranged to electrically connect the support member (2) respectively to each first and each second connection pad, the support member (2) including a thermal conductor configured to transfer heat from the hot source (Sc) to the first metal connector, and to transfer heat from the second metal connector to the cold source (Sf).
