圆形纬编针织物电极导电性能及电阻理论模型构建

为从理论上指导基于纬编针织物电极智能腿套的设计,建立电阻模块理论模型,选用2种导电材料、3种组织结构和4种电极尺寸制作了24种腿套试样,测试其热定形前后腿套电极部位的导电性能,探讨不同因素对织物电极等效电阻的影响,同时建立织物电极等效电阻线性拟合模型。结果表明:不同因素对织物电极导电性能均有显著影响,且原料对导电性能影响最显著;镀银纱织物热稳定性较好,对于需热定形处理的导电织物可选用镀银锦纶纱为原料;建立的电阻模块理论模型可用于定量分析和预测织物电极的等效电阻。

Electric conduction and resistance theory model of circular weft knitted electrodes

In order to provide theoretical guidance for designing leggings with circular weft-knitted electrodes,based on the loop structure of knitted fabrics,a theoretical model of resistance module was established,with 2 types of conductive materials,3 knitted structures and 4 electrode sizes,totaling 24 leggings.The leggings were knitted and treated by heat setting to analyze the electric conduction of knitted electrode,for exploring the influence of different factors on the electric conduction of knitted electrodes and establishing a linear fitting resistance model of knitted electrodes.The results show that different factors have significant influence on the conductivity of flexible electrodes,among which conductive material has the most significant influence.Heat setting has little effect on the electric conduction of flexible electrodes knitted by silver plated yarn therefore it can be used as the material for flexible knitted electrodes that need to be heat-set.The theoretical model of resistance module can be used to analyze and predict quantitatively the resistance of the knitted electrodes.
