Abstract
This paper examines new approaches in the synthesis of carbon dioxide gas sensors using conductometry. Since 2020, conductive sensors have experienced significant growth due to their specific advantages. These sensors are divided into thermal and electrical categories, each offering specific benefits depending on application needs and environmental conditions; if accuracy and rapid response are crucial, thermal conductive sensors are a better option; however, if cost and compatibility with electronic systems are a priority, electrical sensors can be a suitable choice. Nanomaterials such as metal oxides and polymer nanoparticles are recognized as advanced sensing materials, providing improvements in selectivity, sensitivity, and response time. The study also addresses the conductive properties of nanocomposites and the impact of nanoparticles on them, discussing the advantages and disadvantages of each sensor technology. Studies have shown that metal oxides possess significant conductivity at high temperatures around 600°C.
