A finite element formulation is developed for laminated composite plate bonded with piezoelectric layers. To improve the accuracy of the prediction of the plate deformation, a high order shear deformation theory is used, whereas the through-the-thickness linear temperature field distribution is assumed. For the electric potential, a new high order theory has been used. Numerical results of a piezoelectric laminated plate show the significant impact of piezoelectric coupling and pyroelectric effects on the sensory response. Furthermore, the pyroelectric effects will influence the transverse shear stress insignificantly.
