“…Compared to other sensing materials, metal oxide semiconductors possess low cost, simple construction, small size, and easy installation. Recently, with the advantages of large surface area, high surface to volume ratio, and special physicochemical properties, metallic oxide nanostructures such as SnO 2, TiO 2 , ZnO and CeO 2 have attracted wide interest for being used as humidity sensing materials [8][9][10][11] . Although lots of progresses on humidity sensors have been obtained, there are still some shortcomings in humidity sensitive materials such as low response speed and poor stability.…”

“…However, the sensors incorporating doped tin oxide require an elevated temperature (≥ 200 ˚C) for their optimum operation (Berry andBrunet 2008, Hieu et al 2008). In addition, the sensor operation at elevated temperature itself causes gradual changes in the tin oxide film properties, which in turn deviate gas sensing properties of the device with time (Hu et al 2003, Kuang et al 2007. Therefore, it is highly desirable to have sensors, which can operate at room temperature, but having comparable properties with that of tin oxide for gas sensing.…”

“…Relative humidity (RH) measurements and controls play an important role in many fields, such as meteorology, agriculture and electric device storage [1,2].The performance of a humidity sensor mainly depends on its sensing material, so we may conclude that sensing material is the core of a good humidity sensor. In the past decades, many kinds of materials including polymer [3][4][5][6], electrolytes [7][8][9], organic-inorganic hybrid composites [10][11][12][13], photonic crystal [14][15][16] and metal oxides or ceramic [17][18][19][20][21][22] have been explored to fabricate humidity sensing detectors.…”
