Transversal Stress Sensing of Fiber Bragg Grating Embedded into Metal Component
Optical fiber smart metal structures can be formed by embedding fiber Bragg grating (FBG) sensors into the metal matrix can. The stress sensing of the FBG is affected by the embedding method and the characteristics of the interlayer and the matrix. FBG sensors with nickel protective coating are embedded into the metal component using soldering method. The theoretical model for embedded FBG’s wavelength trend with external force is developed. Bending tests are carried out to test the transversal stress sensing of the embedded FBG sensors. The experimental results show, that the model is feasible to forecast the transversal stress sensing of embedded FBG.
