Underwater sensing has extraordinary significance in ocean exploration (e.g., marine resources development, marine biology research, and marine environment reconnaissance), but the great difference between the marine environment and the land environment seriously prevents current traditional sensors from being applied in underwater sensing. Herein, we reported a fully hydrophobic ionogel with long-term underwater adhesion and stability as a highly efficient wearable underwater sensor that displays an excellent sensing performance, including high sensitivity, rapid responsiveness and superior durability. Of greater significance, the ionogel sensor showed tremendous potential in underwater sensing applications for communication, posture monitoring and marine biological research.

完全疏水的离子凝胶可实现高效的可穿戴水下传感器和通信器

水下传感在海洋探索（如海洋资源开发、海洋生物学研究、海洋环境侦察）中具有非凡的意义，但海洋环境与陆地环境的巨大差异严重阻碍了当前传统传感器在水下传感中的应用。在此，我们报道了一种具有长期水下附着力和稳定性的完全疏水性离子凝胶，作为一种高效的可穿戴水下传感器，具有出色的传感性能，包括高灵敏度、快速响应和卓越的耐用性。更重要的是，离子凝胶传感器在通信、姿态监测和海洋生物研究的水下传感应用中显示出巨大的潜力。
