Temperature dependent analysis of resistance fluctuations in Taguchi gas sensors

This study is carried out to investigate the temperature dependence of fluctuation-enhanced sensor signals in Taguchi sensors. Sensor resistances measured at 20 Hz in the SP sensors manufactured by FIS Inc. and TGS sensors manufactured by Figaro Inc. have been analyzed. An empirical formula has been developed for calculating the temperature dependence. The empirical formula has the potential of application in real-time sensor signal processing and the optimization of temperature for the best sensing performance.
