摘要

本文设计了一种基于PVDF薄膜的柔性压电触觉传感器，用于三维力测量。该传感器包含四个PVDF薄膜和一个PDMS凸起。建立了触觉传感器的数学模型。并通过有限元仿真和实验分析了该结构的可行性。结果表明，该触觉传感器可以同时测量x轴、y轴和z轴的三维力。通过试验，得到z轴、x轴、y轴的灵敏度分别为（0.436±0.019）V/N、（0.206±0.019）V/N、（0.277±0.019）V/N。同时，触觉传感器的线性度和重复性也很好。1

A flexibility piezoelectric tactile sensor for three-dimensional force measurement

In this paper, a flexibility piezoelectric tactile sensor based on PVDF film was designed for three-dimensional force measurement. The sensor contains four PVDF films and a PDMS bump. Mathematical model of the tactile sensor was built. And feasibility of the structure was analyzed by finite element simulation and experiment. Results showed that the tactile sensor can measure three-dimensional force of x-axis, y-axis and z-axis simultaneously. Through tests, the sensitivity of z-axis, x-axis and y-axis are obtained, (0.436 ± 0.019) V/N, (0.206 ± 0.019) V/N, (0.277 ± 0.019) V/N respectively. Meanwhile, the linearity and repeatability of the tactile sensor are also excellent. ¹
