ABSTRACT:
Various exemplary embodiments, devices, systems, and methods for sensing moisture are disclosed, including at least one moisture sensor that comprises an optical fiber, a long period grating formed in at least a portion of the optical fiber, and a layer of PEI bonded to the long period grating. One exemplary embodiment comprises a system for measuring humidity, the system comprising an optical fiber moisture sensor having a mono-layer of PEI covalently-bonded to an outer surface of said optical fiber, a processor coupled to said optical fiber moisture sensor, and a moisture indicator coupled to said processor.
