A high curvature flexible Bragg grating, in planar technology, is designed, fabricated and
experimentally characterized by employing silica glass. The curvature sensing mechanism …

Many studies have been conducted on the simultaneous measurement of temperature and
strain of different structures by fiber bragg grating (FBG) sensors for structural health …

We propose an air gap fiber Bragg grating (g-FBG) sensor that can measure strain and
temperature simultaneously. The sensor is made by aligning two fiber Bragg gratings …
