摘要：

High-performance and multifunctional gel materials are valuable in the field of bio-signal monitoring, but their application in underwater environments still faces great challenges. Herein, we have designed a biological electrode based on UV-crosslinked gel with excellent anti-swelling property (SR < 140%), underwater conductivity and underwater adhesion for application in aquatic environments. The gel is subjected to solvent exchange in the aqueous environment causing hydrophobic aggregation, leading to the presence of hydrophobic interactions and zwitterionic electrostatic adsorption. Particularly, the gel electrode exhibits stable mechanical properties and low impedance (40.2 omega) in the aqueous environment. The gel electrode obtains high quality underwater ECG signals and possesses better sensitivity (0.498) than the commercial electrode, and the RMS noise (7.53 mu V) is lower than the commercial electrode even after being immersed in water for 7 days. Therefore, we believe that the designed gel electrode is promising for application in the field of underwater wearable biosensor. [GRAPHICS]
