Summary

Piezoelectric materials are noncentrosymmetric materials which show coupling of mechanical and electrical properties. The characteristics of these materials in giving rise to a potential when strained or a strain induced displacement when subjected to a varying electric potential, gives rise to a variety of useful applications such as sensors, actuators, transducers etc. Interestingly, many ferroelectrics have also found useful applications in such applications mainly because of their superior piezoelectric properties.
