【摘要】：为满足集成针织柔性传感器的智能无缝内衣对于传感性能的要求,结合提花添纱编织技术,采用不同导电纱线作为原材料制备了不同传感区尺寸的针织柔性传感器.通过定伸长拉伸试验考察了针织柔性传感器的电阻-应变关系及重现性,并采用正交试验分析了影响传感器灵敏系数的因素.结果表明,当针织柔性传感器的应变小于15%时,不同线密度的镀银锦纶丝、镀铜锦纶丝针织柔性传感器的电阻与应变均呈线性关系,其重现性良好,适宜作为编织针织柔性传感器的导电材料.影响镀银锦纶丝传感器灵敏系数的显著性因素依次为:镀银锦纶丝线密度、横列数、横列数与纵行数的交互作用,在设计传感区尺寸时,横列数比纵行数更为重要.含铜腈纶纱和含铜腈纶/涤纶混纺纱针织柔性传感器的电阻与应变只在小应变(≤2%)时才能满足线性关系,因此不能作为导电材料用于针织柔性传感器的编织.
[Abstract]:In order to meet the requirements of intelligent seamless underwear with integrated knitting flexible sensor for sensing performance combined with jacquard yarn weaving technology different conductive yarns were used as raw materials to prepare knitted flexible sensors with different sensing area sizes.The resistance strain relationship and reproducibility of the knitted flexible sensor were investigated by the constant elongation tensile test. The factors affecting the sensitivity coefficient of the sensor were analyzed by orthogonal test.It can be used as conductive material for knitting flexible sensor.The significant factors influencing the sensitivity coefficient of silver-plated nylon fiber sensor are as follows: the density of silver-plated nylon yarn, the number of transverses, the interaction between the number of transverse lines and the number of longitudinal lines. In designing the size of sensing area, the number of transverse lines is more important than the number of longitudinal lines.The resistance and strain of the flexible sensor of acrylic yarn containing copper and acrylic / polyester blended yarn containing copper can only satisfy the linear relationship when the strain is less than 2, so it can not be used as conductive material for knitting flexible sensor.
