Description
Xianhuan Luo and six colleagues model how much strain a glued-on fibre sensor feels when the structure beneath it stretches. Fibre Bragg grating sensors watch wind turbine blades for damage, prized for small size and immunity to electrical noise. The catch sits in the glue: the adhesive layer between blade and fibre absorbs part of the strain, so readings understate it. Their 2026 paper builds a model for the end-bonded layout, where the sensor is fixed at its ends.
The model spells out how the glue's stiffness, its Poisson behaviour, and its thickness drain transfer efficiency, along with the sensor's gauge length. Finite element simulations, a stress test, then checked the formulas. Both routes agreed on the governing patterns. The authors offer the model as a design guide: choose glue and geometry on paper, and the sensor on the blade reports strain more faithfully.
