不锈钢纤维织物的电阻与应变关系

A Study on the Relation between Resistance and Strain Based on Stainless Steel Fabric

摘要:

设计了2种针织结构，通过拉伸实验观察到不锈钢织物的电阻与应变在一定应变范围内成一线性关系，纺织结构的变化将改变应变传感的线性范围和灵敏度。织物的传感机理是拉伸过程中纱线间接触电阻的变化引起织物电阻的相应变化，通过实验和理论分析，这种不锈钢织物可用于各工程领域的应变测量。

Abstract:

In this paper, two knitting structures are designed and tested. It is observed that the resistance of Stainless Steel (SS) fiber fabric has a linear relationship with strain within a definite range. Any change in fabric structure may cause changes of the linear range and sensitivity of the strain sensor. The main mechanism of the fabric sensitive to strain has been deduced to be the change of contact resistance between yarns during stretching.
