Researchers in various physical sciences survey recent study and applications of piezoelectric materials, which they characterize as solid substances with the capacity to produce an internal electric charge in response to external mechanical stress, notably, electricity created by pressure and latent heat. They cover types, properties, and characteristics of piezoelectric materials; fabrication approaches for piezoelectric materials; nanogenerators based on piezoelectric materials; phototronics based on piezoelectric materials; piezoelectric composites and their applications; piezoelectric materials for biomedical and energy harvesting applications; piezoelectric thin films and their applications, bulk lead-free piezoelectric perovskites and their applications, and piezoelectric materials for sensor applications.
