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
