We have reviewed humidity sensors based on various materials for both relative and
absolute humidity, including ceramic, semiconducting, and polymer materials. In the majority …

A detailed study is reported of the synthesis and characterization of a ZnO–TiO2
nanocomposite and its application as a humidity sensor. Variations of resistance with …

In the present work, multilayered sensing films were prepared by sol–gel spin coating
process using precursor solutions of cobalt oxide and cobalt titanate. Cobalt oxide films …

Nanocrystalline (Mg–Zn–Ti) oxide films were deposited on an equilateral prism using sol–
gel spin process and then annealed at 450° C for 4h. The humidity sensing properties of the …

This paper reports a comparative study of an optical humidity sensor based on titania films
fabricated by sol–gel and thermal evaporation methods. As semiconducting oxides are …

Present paper reports the synthesis of SnO2–TiO2 nanocomposite, its characterization and
performance as opto-electronic humidity sensor. Nanocrystalline SnO2–TiO2 film was …

Thin films of titanium dioxide in anatase form have been prepared using isobutyl titanate as
precursor. The resulting TiO2 was coated on an U-shaped pyrex glass rod to sense the …

Present paper explores the synthesis, characterization, and opto-electronic humidity as well
as liquefied petroleum gas (LPG) sensing applications of iron titanium oxide nanocomposite …

This paper reports the humidity sensing behaviour of sol–gel processed ZnO films deposited
on U-shaped borosilicate rods as substitute of optical fiber having the same radius of …

This paper reports the synthesis of SnO 2-CuO, SnO 2-Fe 2 O 3 and SnO 2-SbO 2
composites of nano oxides and comparative study of humidity sensing on their electrical …
