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

A relative humidity sensor based on a graphene oxide-coated few-mode fiber Mach-
Zehnder interferometer (MZI) is proposed in this paper. The MZI was made by splicing a …

Hydrogel-integrated optical fiber sensors have garnered momentous interest due to their
optical properties, biocompatibility, and biodegradability. Integrating active materials with …

Whispering gallery mode resonators (WGMRs) have achieved significant results due to their
unique properties such as extremely small mode volume, ultra‐high quality (Q) factor, fast …

In this paper, a carboxymethyl cellulose (CMC)/carbon nanotubes (CNTs) composite film
was manufactured and used as a good humidity sensitive material to design a humidity and …

The refractive index (RI) is a significant optical measurement since it encapsulates the
substance's optical properties. The proposed sensor demonstrates a novel, simple and …

A high sensitivity humidity fiber sensor based on all-agar Fabry-Perot (FP) interferometer is
proposed and experimentally demonstrated. The sensor is fabricated by filming a thin layer …

Humidity is among the most important environmental factors which enhance the biogenic
acidic corrosion in concretes of sewers structures. Deterioration of concrete structures is a …

In this work, we introduced fabrication and interrogation of simple and highly sensitive fiber-
