“…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.…”

In this paper, we report the synthesis and characterization of composites of polyaniline and aluminum doped tin oxide (AlSnO 2 /PANI) nanofibers for hydrogen gas sensing application. Al-SnO 2 /PANI composite nanofibers have been fabricated via electrospinning technique and subsequent calcination procedure. The as-prepared Al-SnO 2 /PANI composite nanofibers were investigated for structural characterizations by means of SEM, FTIR, UV-VIS and XRD. SEM revealed the nanofibers with the diameter around 200-300 nm formed a non-woven material with highly porous and agglomerated structure. FTIR and UV-VIS spectra revealed the possible incorporation of Al-SnO 2 in PANI and confirmed the uniform attachment of PANI on the surface of Al-SnO 2 nanostructures. XRD showed peak broadening and the peak positions shift from standard values, indicating presence of aluminum doped tin oxide in nanoparticles form in the polyaniline (PANI) matrix. On exposure to hydrogen gas (1000 ppm), it was found that the nanofibers of Al-SnO 2 /PANI composite showed high sensitivity at 48 o C with relatively faster response/recovery as compared to pure SnO 2 and Al doped SnO 2 nanofibers.

“…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.…”

CeO 2 -NiO composites were prepared by a simple grind method followed by a heat-treatment process and characterized by X-ray diffraction, transmission electron microscope and nitrogen adsorption-desorption test. Humidity sensing properties of CeO 2 -NiO composites with different mass ratios were studied. The optimal result was obtained for the sample with CeO 2 -NiO mass ratio of 0.5. The impedance of the sensor changes more than five orders of magnitude within the humidity range from 11 to 95 % relative humidity (RH) at 100 Hz. The response and recovery time are about 3 and 19 s respectively, and the maximum hysteresis is \2 % RH. The results indicate the potential applications of CeO 2 -NiO composite (CeO 2 -NiO mass ratio of 0.5) for fabricating high performance humidity sensors.
