A humidity sensing material is usually hygroscopic in nature and can allow sites for water adsorption. The hygroscopic material is usually coated in various devices for sensing enhancement. A zinc oxide additive-enhanced nanostructure (ZnO-HMT) was coated repeatedly on fiber Bragg grating (FBG) have...
