With the advent of the intelligence era, flexible piezoelectric tactile sensors are the key components for sensing information and sending signals. The performance parameters of piezoelectric sensors are closely related to the selection of piezoelectric materials. Compared with conventional piezoelectric materials, polyvinylidene fluoride (PVDF) has significant advantages in flexibility, stretchability, chemical stability, electromechanical conversion, ease of use, and acoustic propagation impedance. As a result, PVDF has become a popular topic of research. This paper introduces the working principle of piezoelectric materials and flexible piezoelectric sensors based on PVDF materials and details the research progress of different materials based on PVDF for the preparation of flexible piezoelectric tactile sensors, such as: PVDF and its copolymers for the preparation of flexible piezoelectric sensors and PVDF doped with other functional materials for the preparation of flexible piezoelectric sensors. In this paper, the advantages and disadvantages of different materials and the development prospects of PVDF flexible piezoelectric sensors are summarized to provide some insights for high-performance flexible PVDF piezoelectric sensors.

基于 PVDF 的柔性压电触觉传感器：回顾

随着智能时代的到来，柔性压电触觉传感器是感知信息和发送信号的关键部件。压电传感器的性能参数与压电材料的选择密切相关。与传统压电材料相比，聚偏二氟乙烯（PVDF）在柔韧性、拉伸性、化学稳定性、机电转换、易用性、声传播阻抗等方面具有显着优势。因此，PVDF已成为研究的热门话题。本文介绍了基于PVDF材料的压电材料和柔性压电传感器的工作原理，详细介绍了基于PVDF的不同材料用于制备柔性压电触觉传感器的研究进展，如：PVDF及其共聚物用于制备柔性压电触觉传感器传感器和PVDF掺杂其他功能材料用于制备柔性压电传感器。本文总结了不同材料的优缺点以及PVDF柔性压电传感器的发展前景，为高性能柔性PVDF压电传感器提供一些启示。
