Abstract：Objective To explore the feasibility of replacing the conventional Ag/AgCl electrocardiogram (ECG) electrode with the new silver fiber fabric ECG electrode. Methods Compared with the conventional Ag/AgCl ECG electrode, a new type of silver
fiber fabric ECG electrode was prepared to improve the anti-perspiration and anti-oxidation properties of silver fiber fabric. Twenty volunteers were recruited for skin tolerance test. The commonly used Ag/AgCl ECG electrode was selected as the control electrode,
numbered as the test electrode 1, the silver fiber fabric ECG electrode numbered as the test electrode 2, and the silver fiber fabric ECG electrode which was covered by conductive hydrogel numbered as the test electrode 3. Results After improvement, the
conductivity of silver fiber fabric was increased. The diagonal resistance of 20 cm×20 cm silver fiber fabric decreased from 2.3 Ω to 0.9 Ω after high temperature pressing. Using conductive hydrogel to reduce the impedance between electrodes and skin, the problem
of skin dryness was solved. The sweat resistance of the improved silver fiber fabric had been greatly improved. The skin tolerance of electrode 2 and electrode 3 was better than that of electrode 1, but there was no significant difference between electrode 2 and
electrode 3; the voltage attenuation of test electrode 2 was large, and the performance of electrode 2 was poor. Both electrode 1 and electrode 3 were close to the original signal, and the electrode performance was good. Conclusion The electroconductive hydrogel
coated with silver fiber fabric can solve the problem of skin damage on the basis of the normal collection of ECG. The research results in this study have practical value.
