Why the study?
Commercially used Ag/AgCl electrodes have drawbacks that become more obvious in long-term ECG monitoring, motivating the development of new types of electrodes.
Do textile and graphite-based electrodes provide comparable or improved ECG signal fidelity and durability compared to standard Ag/AgCl electrodes?
Do textile and graphite-based electrodes provide comparable or improved ECG signal fidelity and durability compared to standard Ag/AgCl electrodes?
Textile and graphite-based electrodes offer promising, durable alternatives to traditional Ag/AgCl electrodes for long-term wearable and underwater ECG monitoring.

May inform wearable ECG electrode development; leaves open human translation from animal data.
Long-term electrocardiography (ECG) monitoring can scrutinize human health, which is very essential for the early detection and treatment of cardiovascular disorders. For present, commercially used silver/silver chloride (Ag/AgCl) electrodes have drawbacks, and these would be more obvious in long-term monitoring. Therefore, people are developing new types of electrodes for ECG from different perspectives. At present, innovations are made: 1) Applying conductive thread into sewing to make textile electrodes for wearable ECG monitoring. 2) New material (Graphite Based Electrode) replacing the conventionally used Ag/AgCl.
