Acceleration of chemo-sensory information processing using transient features

A snapshot from the steady-state response of chemical sensors conveys, on average, more mature and relevant information regarding the analyte than a snapshot from the transient can provide. Nevertheless, time constraints in many applications make it infeasible to wait for and extract steady-state features. Substituting them by transient ones is the only viable solution to accelerate odor processing. Based on measurements recorded from metal-oxide sensors, we point to a correlation between a transient feature and the steady-state resistance that are observed in response to fixed analyte concentration. We utilize this correlation to expedite standard quantification and classification substantially while ensuring the performance that the steady-state feature can provide.
