Films of piezoelectric poly(vinylidene fluoride) (PVDF) and its copolymer P(VDF-TrFE) have been studied intensively for their potential application in piezoelectric sensing devices. The present work focuses on tuning the piezoelectric properties of P(VDF-TrFE) films via incorporating Ag and polydopamine co-decorated PZT (Ag@PDA@PZT) particles. Ag@PDA@PZT particles can effectively improve the β-phase content and piezoelectric properties of P(VDF-TrFE) films. The highest open-circuit voltage and short-circuit current of P(VDF-TrFE)-based flexible pressure sensors incorporating Ag@PDA@PZT particles are ~30 V and ~2.4 μA, respectively. The flexible sensors exhibit a response to different body movements, providing a practical and potentially useful basis for human-machine interface applications.
压电聚偏二氟乙烯（PVDF）及其共聚物P（VDF-TrFE）薄膜因其在压电感测装置中的潜在应用而受到广泛研究。目前的工作重点是通过掺入银和聚多巴胺共修饰的PZT（Ag@PDA@PZT）颗粒来调节P（VDF-TrFE）薄膜的压电性能。Ag@PDA@PZT颗粒可以有效地提高P（VDF-TrFE）薄膜的β相含量和压电性能。掺入Ag@PDA@PZT颗粒的基于P（VDF-TrFE）的柔性压力传感器的最高开路电压和短路电流分别约为30 V和~2.4 μA。这些柔性传感器对不同的身体运动表现出响应，为人机接口应用提供了实用且潜在有用的基础。
