Washable and Flexible Screen-Printed Ag/AgCl Electrode on Textiles for ECG Monitoring

Electrocardiogram (ECG) electrodes are important sensors for detecting heart disease whose performance determines the validity and accuracy of collected original ECG signals. Due to large drawbacks (e.g., allergy, shelf life) traditional commercial gel electrodes, textile receive widespread attention their excellent comfortability breathability. This work demonstrated a dry electrode monitoring fabricated by screen printing silver/silver chloride (Ag/AgCl) conductive ink on ordinary polyester fabric. The results show that screen-printed have good stable electrical electrochemical properties signal acquisition performance. Furthermore, resistance is maintained within 0.5 Ω/cm after 5000 bending cycles or 20 washing drying cycles, exhibiting flexibility durability. research provides favorable support design preparation flexible wearable electrophysiological sensing platforms.
