| Abstract | Conductive hydrogels have shown great promise in wearable electronics due to their inherent advantages of flexibility, biocompatibility and conductivity. However, current research efforts on hydrogel-based wearable sensors primarily focus on terrestrial applications, adapting conductive hydrogels for underwater sensing remains a significant challenge. Herein, a robust, durable, anti-swelling and highly conductive hydrogel composed of poly (N-acryloyl glycinamide) and silver nanoparticles (PNAGA/Ag NPs) is prepared by a straightforward one-pot polymerization and reduction technique for underwater sensing and communication purposes. The effective incorporation of Ag NPs, facilitated by the high solubility of silver nitrate (Ag NO) in the pre-gelation solution, imparts the hydrogel with impressive mechanical toughness (3.32 MJ/m), fatigue resistance, and a high electrical conductivity of 4.1 mS/cm. The PNAGA/Ag NPs hydrogel demonstrates excellent performance as a temperature, pressure and strain sensor. The strong dual hydrogen bonding interactions among the bisamide groups on the polymer chains endow the hydrogel with good anti-swelling properties, making the Ag NPs remain stably within the network without expansion or diffusion for over 30 days. Resultantly, the hydrogel sensor is developed to transmit information using Morse code for underwater communication. Through collaboration with machine learning algorithms, the hydrogel sensor achieves real-time language recognition with a high identification accuracy of 100 %. This work successfully integrates anti-swelling characteristics, mechanical robustness, and electrical conductivity within a hydrogel system, offering a viable solution for utilizing hydrogel-based sensors in underwater environments. |
