Abstract:

We propose single-device extraction of the transient response of gas sensors by metal-oxide memristors toward simple processing of transient response in an olfactory sensor array. Gas discrimination was carried out by storing the information of the transient sensor response as memristor resistance. Prior to the discrimination test, the analog reset behavior was confirmed to occur in the voltage range of 0.7 - 2 V, and the transient sensor responses were examined to be different between the test gases of acetone and ethanol. By applying a pulse train corresponding to the sensor outputs to the memristor, significantly different memristor resistances were obtained between the gases even under the condition that the discrimination was difficult by the steady-state outputs. Consequently, we successfully discriminated the gases based on the transient responses extracted by the memristors, demonstrating promising properties of our proposal for transient-based olfaction.
