Description
Summary:[Display omitted] •The adding of bioionic liquid improves conductivity and underwater adhesion of gels.•The gel electrode exhibits low impedance at physiologically relevant frequencies.•The noise of the gel electrode is much lower than the commercial gel electrodes.•The gel electrode effectively reduces the influence of motion artifacts.•It obtains real-time high-quality bioelectric signals in the underwater environment. Bio-adhesive and ion-conductive hydrogels are of great significance in the field of bioelectric monitoring, but many challenges remain for practical applications in complex conditions and underwater environments. Here, we report a bioelectrical electrode based on ion-conductive gel with excellent water-resistant, underwater adhesion, and swelling resistance for application in the aquatic environment. Especially, the gel electrode exhibits extremely low impedance (
