Abstract

In this paper, a knittle pressure sensor was designed and fabricated by coating graphene/Polyvinylidene Fluoride nanocomposite on the knitted polyester substrate. The coating was carried out by a dip-coating method in a nanocomposite solution. The microstructure, surface properties and electrical properties of coated layers were investigated. The sensors were tested under the application of different pressures, and the corresponding sensor signals were analyzed in terms of resistance change. It was observed that the change in resistance was 55% kPa with a sensitivity limit of 0.25 kPa. The sensor model was created and simulated using COMSOL Multiphysics software, and the model data were favorably compared with the experimental results. This investigation suggests that graphene-based nanocomposites can be used in knittle pressure sensor applications.

摘要

在本文中，通过在针织聚酯基底上涂覆石墨烯/聚偏氟乙烯纳米复合材料，设计并制造了一种针织压力传感器。涂覆是在纳米复合溶液中采用浸涂法进行的。研究了涂层的微观结构、表面性质和电学性质。在不同压力作用下对传感器进行测试，并根据电阻变化分析相应的传感器信号。观察到电阻变化为55%kPa，灵敏度极限为0.25kPa。使用COMSOL Multiphysics软件创建并模拟了传感器模型，并将模型数据与实验结果进行了良好的比较。这项研究表明，基于石墨烯的纳米复合材料可用于针织压力传感器应用。
