“…, environmental noises). 83 Furthermore, systems based on materials such as metal oxide semiconductors, 84,85 conducting polymers, 86,87 and carbon nanotubes 88,89 have shown benefits when the sensitivity and specificity for a given sensing gas were considered, relying on the physico-chemical characteristics of the materials for changes in performance; 90 however, they also show limited stability. Moreover, analysis showed that their thermodynamical decomposition leads to low sensitivity during the sensing measurements, as well as difficulties during their integration in the fabrication and reproduction of the sensor formed with these materials.…”
