导电复合纱基柔性电阻式应变传感器的研究进展

doi:10.19398/j.att.202108031

摘要/Abstract

摘要： 为系统分析导电复合纱基柔性电阻式应变传感器的研究现状,根据复合纱使用的导电材料种类,将导电网络分为一元、二元及多元结构,并对其应变传感性能进行总结和分析,同时研究了多元导电材料之间的协同作用机制。一元结构复合导电纱受导电材料维度结构的影响,形成差异化导电网络结构,但难以同时实现高应变范围和敏感性;二元及多元结构导电纱由不同维度导电材料构建,形成了点-线-面、点-点、线-线、面-面等不同连接方式的三维导电网络,能够在大应变范围内实现高敏感性,并提高传感器的稳定性。该研究为多元应变传感网络的构建新途径提供重要的参考依据。

Abstract: In order to systematically analyze the current research status of the flexible resistance-type strain sensor based on conductive composite yarns, the conductive networks are divided into one-element, two-element and multi-element conductive structures according to the types of conductive materials used in the preparation. The strain sensing performances are summarized and analyzed. At the same time, the synergistic mechanisms between different conductive materials are studied. The composite conductive yarns of the one-element structures are affected by the dimensional structures of the conductive materials, forming the differentiated conductive network structures, but it is difficult to achieve high strain range and sensitivity at the same time. Conductive yarns with binary and multiple structures are constructed of conductive materials with different dimensions, forming the three-dimensional conductive networks with various connection modes such as point-line-surface, point-point, line-line, surface-surface, etc., which can achieve high sensitivity in a large strain range, and improve the stability of the sensor. This research provides an important reference for a new approach to construct the multivariate strain sensing network.

Key words: conductive nanomaterials, conductive yarns, flexible resistance-type strain sensor, preparation method, sensing performance
