## Abstract We present a potential sensor head for the simultaneous measurement of temperature and strain based on the concatenation of two longβperiod fiber gratings arcβinduced in different fibers. Despite being the temperature and strain sensitivities of the individual gratings well defined, we
## 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 archβshaped steel strip. The grating in concave and convex position ex
