Problems solved by technology

In Chinese patent 200610147211, conductive fibers with dual functions of information perception and transmission, that is, carbon nanotube modified polyurethane fibers, are woven into fabrics as weft yarns to form flexible sensing fabrics, but this method requires weft yarns to run through the width of the fabric, and requires To maintain continuity, the sensing fabric cannot be cut in the warp direction; at the same time, it is also required that the conductive fibers are separated by insulating yarns, and only the information sensing function of the conductive fibers is used to realize the strain sensing; in addition, the used in this method Conductive fibers have higher resistance, with a resistivity of 10 8 Ω·cm, making the fabric less sensitive
