The chemiresistive sensor array mimicking the olfactory receptors chemically reacts with gas molecules to generate different electrical signals with unique waveforms. The measurement and monitoring system serve as the function of olfactory bulb and tract which separately relay and transmit the signals to the limbic system. The mathematical feature engineering and deep learning analysis mimic the human olfactory perception properties of limbic system in the cerebrum such as piriform cortex, amygdala and hippocampus.
