Origin of Baseline Drift in Metal Oxide Gas Sensors: Effects of Bulk Equilibration

Origin of Baseline Drift in Metal Oxide Gas Sensors: Effects of Bulk Equilibration

Metal oxide (MOX) gas sensors and gas sensor arrays are widely used to detect toxic, combustible, and corrosive gases and gas mixtures inside ambient air. Important but poorly researched effects counteracting reliable detection are the phenomena of sensor baseline drift and changes in gas response u...
