    Electronic nose technology is a research field that has developed rapidly in recent years.


    In the past 40 years, researchers have been committed to research in this field


    The electronic nose is a simulated biological olfactory system composed of a sensor array combined with a pattern recognition system


    The structure of the electronic nose is very similar to the structure of biological olfaction.

    The signal preprocessing is equivalent to the olfactory neuron, which filters and exchanges the response pattern of the sensor array to complete the feature extraction


    Pattern recognition is equivalent to the human brain.
