Abstract
Textile-based electrodes are a potential choice for wearable and continuous monitoring of electrocardiogram measurements. In this paper, we present a novel composite textile electrode for ECG measurement. We chosen cotton jersey knit fabric as the substrate. Based on the substrate, polypyrrole (PPy) was coated chemically only and plated chemically electrochemically successively, respectively, to form PPy/cotton fabric composite electrode. The obtained results suggest that, first, both the composite electrodes can measure the ECG signals including P-waves, QRS complex and T-waves clearly, second, both the composite electrodes are poorer frequency dependence than Ag/AgCl electrode, and the one deposited chemically only is the poorest, whats more, the composite electrode deposited chemically only obtains the highest signal to noise ratio (SNR).
