Abstract Water molecules are ubiquitous disruptors of conventional gas sensing materials, often leading to diminished performance in materials that reliant on electronic signal transmission. This creates the pressing need for efficient with anti‐humidity interference properties. Here, a hammerhead shark‐inspired microvillus‐structured ionic elastomer based transmission nanoconfined space is constructed by incorporating liquids into polymer matrix. The elastomers optimized microvillus structure demonstrated 1.68‐fold higher response than flat ones, short time (9 s) toward 30 ppm triethylamine (TEA), excellent selectivity and low limit detection (LOD) (104.56 ppb). Such serves as proof‐of‐concept effectively combining solvated ion transport design develop advanced systems. With such an evident (23.52%), similar (12 s), LOD (498.05 ppb), long‐term stability (at least days) achieved at relative humidity 70%. Mechanistic investigations revealed effective ions facilitated after sequential water TEA surroundings while significantly enhanced transport. Furthermore, utility system shrimp decay monitoring under wet conditions.

Abstract The rapid growth of human society and the necessity protecting health security underscore importance identifying toxic gases emitted by industrial sectors. Ammonia (NH 3 ) is a widely produced colorless gas with strong odor, coupled its harmful environmental impacts, such as contributing to air pollution (PM 2.5 formation) severe impact on respiratory system body, even at low concentrations. Covalent Organic Frameworks (COFs) have emerged revolutionary materials address these current issues. crystalline porous network through dynamic covalent chemistry COFs possesses versatile structural chemical properties that make them ideal for sensing. This review provides comprehensive overview latest advancements in COF‐based sensors focus ammonia Moreover, detailed discussion about design synthesis methods their important characterization techniques presented. It concludes providing future outlook developing advanced COF sensing applications.
