Coupled electro-thermo-elastic equations applicable for the analysis of smart structures have been derived. These governing equations have been used to obtain the deformation of a smart beam under the action of external mechanical load and an electric potential. The results of the present study have been compared with those available in literature. The present study brings out the essential difference between sensing and actuation phenomena by solving for the electric potential and the deformation variables in the piezo material.
