Development of Piezoelectric Elastomers and Their Applications in Soft Devices

Abstract

Piezoelectric materials have wide-ranging applications owing to their capacity to convert mechanical energy into electrical energy in daily life scenarios. With rapid development in fields such as wearable electronics, intelligent electronic products, and medical equipment, the requirement for the elasticity of piezoelectric materials has become increasingly stringent. However, combining high piezoelectric performance with high elasticity in most conventional piezoelectric materials is challenging, limiting the application of piezoelectric elastomers in complex scenarios. Recently, several piezoelectric elastomer materials with good flexibility, high elasticity, and easy processing ability have been reported, and their applications in soft devices have rapidly developed. In this review, the current state of piezoelectric elastomers and their applications are systematically reviewed. Additionally, an overview of trends in the development of piezoelectric elastomer materials is given, providing a reference for future research in this field.
