Abstract :
Experimental studies on humidity measurements by using a FBG-based humidity sensor with multi-layer polyimide coating are demonstrated. The preliminary experiments for investigating the performances of this polyimide-coating humidity sensor are carried out and several experimental results in measurements of the relative humidity and moisture in oil are presented.
