## Abstract An embedded dual fiber Bragg gratings sensor for simultaneous measurement of temperature and load (strain) is proposed and experimentally demonstrated. Two nearly identical gratings are mounted on opposite side of an arch‐shaped steel strip. The grating in concave and convex position ex
