- 20 - ABSTRACT OF THE DISCLOSURE An optical fiber moisture sensor is prepared by coating an optical fiber with a thin film of plasma polymerized hexamethyldisiloxane and ammonia, approximately 1-2 um thick. The light transmission characteristics of such a coated optical fiber change as a function of moisture conditions in an environment to which the coating is exposed. Accordingly, the coated optical fiber may be utilized for sensing changes in moisture conditions in an environment by being placed in the environment, causing light to be transmitted through the fiber and detecting changes in the light transmitted through the fiber as a function of the moisture conditions in the environment.
