Design Principles From Natural Olfaction for Electronic Noses (Adv. Sci. 12/2025)

Electronic Noses Unlocking “universal smell” requires integrating key principles of natural olfactory systems: modulation of gas transport, utilization of non-selective sensing elements, chemical filters akin to the biological mucus layer to separate compounds, refined context-specific signal integration, and more. These components work in harmony to improve the accuracy, sensitivity, and adaptability of electronic noses whilst mitigating common failure modes.
