Abstract

A basic study was conducted to manufacture conductive composite threads for use in textile-type electrodes and circuits for smartwear that can be sewn, embroidered, and knitted. The two-types of poly(ethylene terephthalate(PET) filament with a circular cross-section(SD), and an oval cross-section and curved surface(DT), and the conductive yarn was selected as a silver-coated polyamide(AP). The samples were produced two-ply PET yarn as the first twist, then using AP as the second twist, and both processes were applied with 100, 200, 500, and 1,000 TPM. As the number of twists increased, the packing density of samples increased, and the bulkiness of DT was decreased. In addition, the elongation at break tended to increase as the number of twists increased, especially for samples manufactured with DT with a curved surface appeared larger. The linear resistance results increased as the number of second twists in which the conductive yarn was twisted increased. It was confirmed that the area of AP exposed to the outside was more prominent in SD-AP, resulting in decreased linear resistance. Based on the results, samples that have the excellent mechanical and electrical performance were selected to manufacture textile-type electrodes that embedded leg sleeves to measure the surface electromyography(sEMG) signal collection performance. The signal-to-noise ratios(SNR) of textile-type electrode manufactured by SD - AP and DT - AP were 4.54 and 14.96, respectively, confirming the possibility of collecting EMG signals. Thus, this study is expected to be applicable to a wider range of fields than smartwear.

应用于智能穿戴的基于扭转工艺的导电螺纹的制造与表征
研究人员进行了一项基础研究,以制造用于纺织型电极和智能服装电路的导电复合线,这些电极和电路可以缝纫、刺绣和针织。采用圆形截面(SD)和椭圆形截面及曲面(DT)两种类型的聚对苯二甲酸乙酯(PET)长丝,导电纱选用镀银聚酰胺(AP)。样品以两股涤纶纱为第一捻,再以AP纱为第二捻,分别用100、200、500、1000支TPM进行加工。随着扭转次数的增加,样品的堆积密度增大,DT的体积减小。随着扭转次数的增加,断裂伸长率有增加的趋势,特别是用DT加工的样品,其弯曲表面显得更大。线阻结果随着第二捻次数的增加而增加。证实了SD-AP中AP暴露在外的面积更突出,导致线性电阻降低。在此基础上,选择具有优异机械和电气性能的样品制作嵌入腿袖的织物型电极,测量其表面肌电(sEMG)信号采集性能。SD - AP和DT - AP制备的纺织型电极信噪比分别为4.54和14.96,证实了采集肌电信号的可能性。因此,这项研究有望适用于比智能穿戴更广泛的领域。
