Experimental study demonstrates reliable gas identification across changing environments using a bioinspired artificial olfactory system, highlighting robust sensory adaptation capabilities.

Key Points

To develop an artificial olfactory nervous system with biologically inspired sensory adaptation mechanisms for reliable gas identification across fluctuating environmental conditions.
Designed an artificial olfactory nervous system integrating receptor neurons, intermediate olfactory neurons, and cortical neurons.
Implemented dynamic sensitivity adaptation in receptor neurons to selectively filter background interference and generate distinct signal patterns for novel gases.
Receptor neurons successfully exhibited rapid responses to familiar gases while filtering out background interference to create distinctive signal signatures for novel stimuli.
The integrated system achieved accurate and reliable gas perception across varied environmental conditions despite being trained under limited initial settings.
