AI Technical Summary
Existing shape sensing systems using Fibre Bragg Gratings (FBGs) face inaccuracies due to core spacing in multicore arrays, high costs for small length measurements, reliance on structure design, and lack of reliability under high stresses, particularly in wind turbine applications, limiting their commercial viability and long-term use.
A self-contained 3D shape sensing device with multiple single-core parallel optical fibre arrays embedded in a discrete composite structure, allowing for precise measurement of wind turbine blade deformations without needing to know the blade's design or experiencing structural stresses, and capable of being easily mounted, unmounted, and refitted, with temperature immunity.
The device provides precise, reliable, and cost-effective measurement of wind turbine blade shapes and deflections, enabling long-term monitoring and control without impairing precision, and can be reused across different blades.
