摘要
为探讨金属涂层机织物作为柔性传感器的传感性能,利用织物强力机和自制电流数据采集系统测试涤纶基金属涂层机织物不同速度下拉伸过程中的电流变化,讨论了电流对拉伸的响应规律,分析了不同拉伸速度对电流响应的影响以及经纬向灵敏度之间的差异。结果表明:涤纶基金属镀层机织物经纬向伸长与电流响应曲线在拉伸速度较高时具有较高的线性度,低速拉伸的电流响应曲线相比高速拉伸线性度差;织物经纬向灵敏度随着拉伸速度的增大而减小,其纬向比经向断裂伸长大,纬向的灵敏度高于经向,低速拉伸时该织物的经纬向均具有较大的灵敏度。
In order to investigate the sensing performance of metal-coated woven fabric as soft sensor,the current variation of the fabric to tension at different tensile speeds was experimentally investigated by means of a fabric tension machine and a self-made current acquisition system.The rule of current response to tension was discussed.The influence of different tensile speeds on the current response and the difference between sensitivity in warp and weft direction was analyzed.The results show that the current response of polyester-based metal-coated woven fabric to the tensile in the warp and weft direction shows high linearity at higher tensile speeds,the current response to the low-speed tensile shows more worse linearity compared with that to higher-speed tensile,and the sensitivity of the fabric to tensile in warp and weft directions will decrease with the tensile speed increase.The fabric shows the better elongation at break in the weft direction than that in the warp direction,the current response in the weft direction shows the higher sensitivity than that in the warp direction,and larger sensitivities exist in low speed stretching process.
