Fiber optic humidity sensor based on silk fibroin interference films

Zbigniew Opilski, Marcin Procek, Salvador Aznar-Cervantes, Jose Cenis, Xavier Munoz


The article presents an inexpensive and simple method of fiber optic interference relative humidity (RH) sensors based on silk fibroin (SF) films. The sensors were made on standard multimode telecommunications optical fibers using dip-coating method and examined using broadband light sources. The measuring stand at which the basic sensor parameters were measured and the measured parameters were presented.
