The chemiresistive gas sensor is one of the prominent types of sensors that can detect harmful gases, such as carbon monoxide (CO), NO2, hydrogen sulphide (H2S), and NH3. The gas sensor comprises sensing material, interdigitated electrodes, and electrical resistance. An active layer is placed...
Chemiresistive gas sensors based on metal oxides have been extensively developed for the electrical detection of gases in environmental monitoring; however, metal-oxide-based gas sensors generally require external/internal heaters to enable the adsorption and desorption of target gas molecules. This ...
