Abstract :
This study is carried out to investigate and demonstrate the possibility of practical applications of commercial Taguchi gas sensors for fluctuation-enhanced chemical sensing of multiple gases. The stochastic resistance fluctuations of the sensors were studied during the burning-in process and during exposure to different gases at different temperatures. The analysis of resistance fluctuations in the gas sensors during and after exposure to gases indicates a strongly enhanced sensitivity and selectivity.
