AI Technical Summary
Traditional physiological electrosensing gels are susceptible to environmental humidity, have insufficient mechanical strength, and poor adhesion in long-term dynamic monitoring, leading to signal attenuation, electrode detachment, and skin discomfort, making it difficult to achieve high-quality, long-term physiological signal monitoring.
A deep eutectic solvent composed of DL-menthol and oleic acid is used to replace traditional water. Combined with N,N-dimethylacrylamide, allyl quaternary ammonium salt and catechol monomers, a three-dimensional network structure with high mechanical strength and excellent adhesion is formed. Through hydrogen bonding and covalent cross-linking, strong adhesion between the gel and the skin and low impedance signal transmission are achieved.
It maintains high adhesion in humid and sweaty environments to prevent electrode slippage, ensuring signal stability and mechanical toughness, while also being biosafety and environmentally friendly, making it suitable for long-term wearable health monitoring.
