Gas Recognition‐Signal Transduction Binary Synergism in Bioinspired 2D Nanoconfined Ionic Membranes Enables Ultrasensitive NH 3 Perception

selectivity, with a theoretical detection limit of 50.14 ppb and a sensitivity of 71.55%/ppm. The gas-ion interaction enhances ion transport by promoting ion dissociation and partially releasing nanoconfinement. Operating at room temperature with an ultralow power consumption of 0.52 µW, this system enables efficient monitoring of fresh food spoilage stages, supporting artificial intelligence-assisted classification. This bioinspired platform provides a new avenue to design integrated olfactory perception systems based on ionic signal transmission to achieve intelligent operation (e.g., food packaging), further promoting the development of living organism-like intelligent systems.
