Piezoelectric materials have several packages in engineering and scientific fields. Piezoelectricity is the characteristic of the material due to which the electrical subject is generated in them when mechanical load is applied. PZT4 and BaTiO₃ are examples of unnatural piezoelectric substances. In this paper the analytic solution is discussed of thermal stresses in a thin rotating transversely isotropic disk consisting of a piezoelectric with variable thickness and density. Seth's idea of transition is implemented to simplify the governing differential equation. The obtained results are presented graphically and quantitatively. On the idea of evaluation, it is far discovered that a disk made of piezoelectric material barium titanate (BaTiO₃) is better than a disk made of PZT4 (piezoceramic). Parameters obtained from this research can be used to design pressure sensors, radar antennae, and many other devices, machines, or structures in engineering applications.
