Literature review on optical fiber sensors. Options with Fiber Gratt grating and tapered fiber implies special materials, equipment and procedure.
A simpler procedure was found in the paper "Polymer optical fiber moisture sensor based on evanescent-wave scattering to measure humidity in oil-paper insulation in electrical apparatus" (https://www.researchgate.net/publication/224360067). The idea is to remove the cladding with acetone and apply different layers of Polyvinyl-PVA (Wood glue).
