摘要：

为探索穿戴压力对纺织结构心电电极采集心电图(ECG)信号质量的影响,开发了基于镀银锦纶丝束和涤纶的平纹和缎纹交织结构的4种导电织物电极。从皮肤-电极接触阻抗、舒适性以及织物方阻与穿戴压力的关系等方面评价了织物电极的性能,并测试了不同穿戴压力(2、5、10 kPa)下4种不同织物电极采集ECG信号的性能。结果表明:在不同穿戴压力下,不同结构的织物电极表现出不同的ECG信号采集能力和舒适性能;随着穿戴压力增加,所测试的导电织物方阻先呈下降趋势,然后趋于稳定,ECG信号质量不断增高;纯导电缎纹结构织物具有更好的透气透湿性,并且舒适性优于平纹结构织物;然而在舒适的穿戴压力(2、5 kPa)下,平纹结构织物电极表现出更好的ECG信号质量。

Abstract:

In order to explore the effect of wear pressure on the quality of electrocardiogram(ECG) signals collected by textile structure ECG electrodes, four conductive fabric electrodes based on plain and satin structure were developed using silver-plated nylon tow and polyester, the performance of the fabric electrode was evaluated from skin-electrode contact resistance, comfort and the relationship between fabric resistance and wear pressure. The ECG signal acquisition performance of four different fabric electrodes under different wearing pressures(2,5,10 kPa) was also tested. The experimental results show that fabric electrodes with different structures are different in ECG signal acquisition capability and comfort under different wearing pressures. As the wear pressure increases, the surface resistance of the conductive fabric first decreases and then stabilizes, and the ECG signal quality is higher. The pure conductive satin structure fabric has better air permeability and moisture permeability, and the comfort ability is better than that of the plain structure fabric. The plain structure electrode shows better ECG signal quality under comfortable wear pressure (2, 5 kPa).

Key words: fabric electrode, electrocardiogram signal, wearable pressure, comfortability
