Method & Evidence

AimTo develop and evaluate a novel conductive hydrogel for ECG electrodes that minimizes skin irritation while maintaining effective signal acquisition.
MethodMaterials science and experimental testing
ProcedureA conductive hydrogel was synthesized using polyvinyl alcohol (PVA), polyethylene glycol (PEG), and graphene oxide (GO) through a cyclic freezing-thawing process. The hydrogel's structure and properties were characterized using techniques like FTIR, NMR, and SEM. The hydrogel was then integrated into ECG electrodes and tested for signal acquisition quality in static and dynamic states. User trials were conducted to compare skin irritation levels with commercial hydrogels over a six-hour period.
