Figure 5. Performance characterization of human ECG monitoring using the SLM-PBS electrodes. (A) Image and schematic of the flexible ECG monitoring device; (B) Comparative ECG signals acquired by the SLM-PBS electrodes and Ag/AgCl electrodes; (C) Heart rate variability monitored by the SLM-PBS electrodes; (D) Scatter plot distribution of R-R intervals in ECG signals collected by the SLM-PBS electrodes; (E) ECG signals recorded by the SLM-PBS electrodes under multi-scenario conditions including standing, lying, working, walking, and running. ECG: Electrocardiogram; SLM: semi-liquid metal; PBS: polyborosiloxane.
