Conductive polymer-coated textile electrodes: (a) PEDOT:PSS and ionic liquid gel-coated polyester textile electrode, adopted from [23]; (b) PEDOT:PSS-coated textile electrode, adopted from [96]; (c) ECG signal collected from PEDOT:PSS-coated textile electrode before washing; and (d) after 50 washing cycle, adopted from [92]. The ECG signals collected using textile electrodes show 25.5 dB SNR before washing and 10.3 dB SNR after 50 washing cycles.
