Abstract
Chemiresistive sensors fabricated using the semiconductor metal oxides (SMOs) are used widely in sensing the hazardous gases and chemicals present in the environment. These sensors are used in medicine, automobile, and electronic industries. Recently, the carbon derivatives decorated with SMOs are considered to be promising candidates for sensing the hazardous constituents in the environment. Among the SMOs SnO2, ZnO, TiO2, and In2O3 are widely used as active medium in the sensors as individual and composite form with carbon derivatives such as single-walled and multiwalled carbon nanotubes. In this chapter, we summarize the current progresses in the field of SMOs, and other polymer composites as active material for sensing of various gases and the chemicals existing in the environment/industrial by-products. Furthermore, we discuss the present challenges in the application of the chemiresistive sensors along with the usage of wireless networking embedded with the sensors.
