摘要: 为实现心电信号的长期穿戴式监测,开发出耐用性能较优的柔性智能纺织品,以棉针织物为基体材料,选用280D镀银导电缝纫线经缝制法制备电子织物。通过正交实验设计,采集在不同缝制参数下电子织物的心电信号,并与临床医用心电进行对比,分析电子织物心电信号的可靠性。并对电子织物导电性、拉伸性、耐磨性和耐水洗性等性能测试。采用Borda数法综合平衡了电子织物的心电信号采集效果及耐用性能,为基于心电信号采集的监护服用电子织物的优化提供基础。

Abstract: In order to achieve the longterm wearable monitoring of ECG (electrocardiogram) signals and develop soft and smart textiles with excellent durability, electronic fabrics were prepared by using cotton knitted fabric as the base material and 280D silverplated conductive sewing thread . Through orthogonal experimental design, ECG signals of electronic fabric under different sewing parameters were gathered and compared with clinical medical ECG to analyze the feasibility of ECG signal. Then, tests of the conductivity, tensile property, abrasion resistance and water washing resistance of electronic fabric were carried out. Borda method was used to balance the acquisition effect of ECG signal and the durability performance of the electronic fabric. This paper provides a basis for the optimization of the electronic fabric based on the ECG signal acquisition.

伴随着老龄化社会的到来,慢性病患者等特殊人群数量的不断增多,据《中国心血管病报告2017》显示,中国心血管疾病的患者约有2.9亿人,死亡率远高于包括癌症、艾滋病在内的其他重大疾病,由于心血管疾病发病具有长期性、累积性和偶发性特征,这就势必要求未来医疗将向日常的健康监测预防转变[12],而基于心电信号采集的监护服可以实现低生理、心理负荷下的实时监控,在医疗卫生领域存在较大的应用前景。
电子织物“隐”于服装之中,整个织物系统可收集敏感信息、监测环境事件并借助无线信道将数据传送至外部网络,以供进一步计算处理,被广泛应用于运动监测、健康监护和国防军事等领域[3]。但是国内外对监护服用电子织物的研究仍很匮乏,目前电子织物的制备方法主要有化学制备法、编织法和缝制法等[4]。……
