Název v původním jazyce

Analytical fluctuation enhanced sensing by resistive gas sensors

Popis výsledku v původním jazyce

Resistance fluctuations across polarised resistive gas sensors were studied in detail to evaluate sensor working conditions for detecting methane and ammonia at various concentrations. The 1/fnoise component typically dominates other noise sources up to a few kHz and can be utilised to improve gas selectivity when compared with measurements of the sensor DC resistance. The Arrhenius plot was created and the activation energy for the investigated gases was evaluated. Using this method, different ambient gases can be potentially detected only by means of a single commercial Taguchi gas sensor and 1/fnoise measurements at different temperatures of the gas sensing layer without a need of intense computations to get reliable results.
