Abstract

As an emerging sensor technology, the flexible piezoelectric sensor has a very wide range of applications. Therefore, in order to achieve better output performance of flexible piezoelectric sensors, it is particularly important to choose piezoelectric materials with good piezoelectric performance. In this study, polyvinylidene difluoride (PVDF)/polyvinyl chloride (PVC)/graphene oxide (GO) composite fibers were fabricated by the electrospinning technique. FTIR and XRD studies showed that the β-phase content of the composite fibers reached 94.6% with the addition of PVC and GO. The mechanical properties of the composite films doped with PVC and GO were also significantly improved. The sensitivity of the sensor made of composite fibers doped with 0.2 % GO reached 16.2 V/N in the range of 1 N. Compared to other systems, the PVDF/PVC/GO system showed excellent piezoelectric output performance with output voltages of up to 6 V and 3 μA by the action of palm tapping. And after 2000 cycles, the sensor system showed good stability. The resulting flexible piezoelectric sensor can monitor actions such as impacts and bending and has great potential for motion monitoring.

基于电纺丝 PVDF/PVC/GO 纤维复合膜的柔性压电传感器，用于人体运动监测

作为一种新兴的传感器技术，柔性压电传感器的应用范围非常广泛。因此，为了使柔性压电传感器获得更好的输出性能，选择具有良好压电性能的压电材料尤为重要。本研究采用电纺丝技术制备了聚偏二氟乙烯（PVDF）/聚氯乙烯（PVC）/氧化石墨烯（GO）复合纤维。傅立叶变换红外光谱和 XRD 研究表明，添加 PVC 和 GO 后，复合纤维的 β 相含量达到 94.6%。掺杂了 PVC 和 GO 的复合薄膜的机械性能也得到了显著改善。与其他系统相比，PVDF/PVC/GO 系统显示出优异的压电输出性能，在手掌敲击的作用下，输出电压高达 6 V，电流为 3 μA。经过 2000 次循环后，传感器系统显示出良好的稳定性。由此产生的柔性压电传感器可以监测冲击和弯曲等动作，在运动监测方面具有巨大潜力。

期刊介绍： "Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad. "Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
