Piezoelectric materials transform electrical energy to mechanical energy and vice-versa making them technologically important as actuators, sensors and transducers in wide ranging applications. New regulations on prevention of hazardous materials in industrial applications have led to a great surge in research on environment friendly alternatives of the commercial Pb-based piezoelectrics – Pb(Zr, Ti)O3. The field of lead-free piezoceramics has seen great advances in the last two decades. This review focuses on the current status of understanding of structure–property relationships in Na1/2Bi1/2TiO3-based lead-free polycrystalline piezoceramics.
