Abstract

This study examines methods for decreasing the response time of chemiresistive, metal oxide microhotplate gas sensors. We describe a successful approach that employs an innovative pulsed-temperature operation methodology for increasing the speeds at which analytes may be recognized. By implementing the suggested strategy, we obtain, in a data-driven fashion, insights into the transduction mechanisms of nanostructured sensing-films that may ultimately guide the selection of modulating frequencies that optimally reduce the sensor-analyte response time while preserving high its discrimination and quantification performance.
