Figure 8.

ECG recordings performed with the PEDOT:PSS/IL textile electrode (in blue), and Ag/AgCl electrode (in red): (a) from volunteers sitting at rest; (b) during movement; (c) percentage of the accuracy of heartbeat detection during different types of activity (seating, standing up, leg moving, arm moving, walking) with textile and Ag/AgCl electrodes; and (d) ECG signal evolutions obtained with textile electrodes in permanent contact with the skin over three days. The inset shows a picture of the skin under the electrode after 72 h. The last ECG signals were obtained from re-used textile electrodes stored in ambient air for one month, adopted from [23].
