Abstract
We present a new sensor configuration based on the intrinsic bend sensitivi ty of Bragg gratings written in D-type fibres. This sensor can be embedded in any layer of a composite material to evaluate curvature in a way indepen dent of axial strain and temperature. It can also be used to measure other parameters such as acceleration, angle and acoustic pressure.
