▎ 摘　　要

This work demonstrated a dry electrode for electrocardiogram (ECG) monitoring based on graphene-coated cotton fabric by screen printing process. The cotton fabric was fully covered by the graphene flakes, which makes the sheet resistance of cotton fabric reaches as low as 42.2 omega/sq. The ECG signals obtained from the graphene-coated textile electrode show comparable performance with the Ag/AgCl electrode under both sitting, standing, and rotating conditions. The Pearson correlation coefficient between the conventional commercial electrode and the graphene-coated textile electrode is 99.47%. The graphene-coated textile electrode exhibited an excellent flexibility with an increase resistance of 4.5% after 1000 bending cycles. The graphene-coated textile electrode after bending showed good performance for ECG signal acquisition.
