We have reviewed the humidity sensors based on ceramic materials. We first discuss the
operating principle of ceramic humidity sensors. This is followed by a section on the …

A wide range of applications such as health, human comfort, agriculture, food processing
and storage, and electronic manufacturing, among others, require fast and accurate …

Optical humidity sensors have evolved through decades of research and development,
constantly adapting to new demands and challenges. The continuous growth is supported …

The present paper reports the detailed study of various metal oxide nanomaterials as opto-
electronic humidity sensor. The sensor elements were fabricated and characterized as thin …

Humidity and moisture sensing is becoming increasingly important in industry and through a
wide spectrum of applications and a review of research activity in the field across a range of …

With diameter close to or below the wavelength of guided light and high index contrast
between the fiber core and the surrounding, an optical microfiber shows a variety of …

A relative humidity fiber sensor based on Fabry–Perot interferometry configuration is
presented. The proposed fiber sensor is functionalized with a thin layer of a moisture …

Aggregate materials have attracted tremendous attention because of their modified or totally
different properties compared with their molecular counterparts. Among various mesoscopic …

Micro-/nanofibers (MNFs) are optical fibers with diameters close to or below the wavelength
