ABSTRACT

 

Gas sensing technology is concerned with development of devices for detection of gases in industries, homes or the environment. Most popular designs employ layer/s of gas sensing materials coated on substrates and connected through electronics to amplifiers. The properties of gas sensing chemicals, the methods to produce them and technologies to assemble them are important factors for manufacturing highly sensitive gas sensors. Rapid developments in materials science research, especially the cross-disciplinary approach of nanotechnology would contribute greatly in this area. This article describes essentials of gas sensing technology, types of sensors, materials used and highlights the possibility of using green chemicals from natural sources for enhanced stability/efficiency of gas sensing materials.
