摘　　要：阐述在人体的指尖处,指纹图案在触觉信号的放大和传递过程中具有重要的作用。受人体指尖结构启发,制备具有仿生指纹结构的挠曲电型柔性压力传感器,通过电耦合测试对传感器的表观压电输出进行研究。结果表明,通过引入仿生指纹结构,可以增强聚偏氟乙烯薄膜的挠曲电效应,相较于无结构的传感器,灵敏度提升了5倍。This paper describes that the fingerprint patterns play an important role in the amplification and transmission of tactile signals for human body.Inspired by the human fingertip structures,it prepares a series of poly(vinylidene fluoride) PVDF-based flexible pressure sensors bearing fingerprint structures and investigate the apparent piezoelectric output of the sensors through electrical coupling tests.The results show that the flexoelectric effect in PVDF can be enhanced by introducing the bionic fingerprint structure,which is 5 times more sensitive compared to the sensor without the structures.
