Abstract: We have calculated the fields of temperature and electric potential in the model of a thermal sensor based on anisotropic thermoelements in the nonstationary thermal regime. It is shown that the effect of thermal-conduction anisotropy of a material of a thermoelement is insignificant at the initial stage of heating, and the distribution of temperature is close to one-dimensional. With further heating, the thermo-physical properties of the substrate have a significant effect on the field of temperature and potential. The use of a substrate with high thermal diffusivity makes it possible to simplify significantly the processing of measurement results and increase the electrical signal of the sensor.
