The robustness of the WPD electrodes. (a) Repeatability tests for 2 weeks with the WPD electrode for ECG biopotential signals; (b) repeatability tests for 2 weeks with the WPD electrode for EMG biopotential signals; the biopotential signal detected for 2 weeks at intervals of 1 week; (c) the PQRST peak in 3-electrode system; (d) the PQRST peak in 2-electrode system; (e) the quantified EMG biopotential signals in 3-electrode system; (f) the quantified EMG biopotential signals in 2-electrode system.
