A novel concept for an intrinsic relative humidity (RH) sensor that uses a tapered fiber Bragg grating (FBG) with zinc oxide nanostructure-embedded coatings is presented. Tests in a controlled environment indicate that the sensor has a linear and stable response behavior at 55% to 80% RH. The tapere...
