The dependence of the center reflection wavelength shift of a resin-embedded fiber Bragg grating (FBG) on the resin material was investigated for the use of the grating fiber as a bending deflection sensor (4 × 8 × 40 mm3). The reflection center wavelength for an FBG embedded in acrylic adhesive shifted linearly by up to 3.1 nm owing to the deflection caused by a bend feeder displacement of 1.2 mm. These wavelength shifts were approximately 60 times larger than those for an etched FBG with one side of the cladding etched to within 11 µm of the core and 33 times larger than those for an FBG embedded in a modified silicon adhesive. These results depend primarily on Young's modulus of the resin material used to embed the FBG.
