This paper summarized the applications of piezoelectric materials on shape control and vibration control of smart structures. The relationships between mechanical and electrical properties on the surface of distributed piezoelectric membrane and the theories of distributed sensitivity/control and hybrid control were described. At first, piezoelectric materials and their phenomenon were elucidated; then the piezoelectric constitutive relations and the theories of mechanics and control on piezoelectric plate and shell were given. Numerical methods and experiment on studying the piezoelectric membrane structures were emphasized. Finally, the future trends of this field were discussed.
