Abstract:

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.

Key words: metal-coated woven fabric, soft sensor, polyester, current response, sensitivity
