The paper discusses thermoelastic thin plates with a microstructure, each microelement having a different temperature, characterized by the term microtemperature. Using the equations of equilibrium of micropolar plates and the equations of the temperature and microtemperature fields, the stress and bending equations of such plates are derived. Equations are written in a form that is suitable for approximate simplifications, considering that in their basic form they are quite complicated and unsuitable for application.
