Figure 1. Schematic illustration of the P-mSnO₂ sensing system for high-performance single-sensor artificial olfaction. (A) Nature-inspired periodic architecture for efficient gas transport and interfacial reactions; (B) Pulse heating-modulated dynamic sensing process (diffusion, adsorption, reaction, desorption) on the periodic mesoporous SnO₂ unit; (C) CNN-assisted high-accuracy discrimination of multiple gases based on enhanced nonequilibrium response signals.
