Abstract
A temperature sensor comprises a thin layer of material the composition of which varies gradually over the layer thickness. The material is superconductive below a critical temperature the value of which depends on the composition of the material. The layer is connected, by means of electrodes to an electronic circuit for supplying current to the sensor and processing a temperature-dependent signal produced by the sensor.
