“…In modern society, gas sensing is a crucial procedure in a variety of tasks, from contamination prevention to toxic molecule detection; all require the aid of gas sensors. − Various sensing materials, metal oxides, conducting polymers, and ceramics, for instance, − have been subjected to meticulous scrutiny. Additionally, sensing targets, such as humidity and toxic chemicals, have been extensively researched. − In particular, research toward high response and selectivity has gained huge interest; a sensitivity as low as 10 ppm has been observed, and a selecting response up to 4000 times its signal has been reported in previous literature. , While sensibility and distinguishability are critical areas of study, this work concentrates on the fundamental issue of the sensing mechanism and the inevitable matter of signal recovery.…”
