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