 abstract={<p>
 Real-time monitoring of deformation of large structure parts is of great 
 significance and the deformation
 </p>
 <p>
 of such structure parts is often accompanied with the change of 
 curvature. The curvature can be obtained
 </p>
 <p>
 by measuring changes of strain, surface curve and modal displacement of 
 the structure. However, many
 </p>
 <p>
 factors are faced with difficulty in measurement and low sensitivity at 
 a small deformation level. In order
 </p>
 <p>
 to measure curvature in an effective way, a novel fibre Bragg grating 
 (FBG) curvature sensor is proposed,
 </p>
 <p>
 which aims at removing the deficiencies of traditional methods in low 
 precision and narrow adjusting. The
 </p>
 <p>
 sensor combines two FBGs with a specific structure of stainless steel 
 elastomer. The elastomer can transfer
 </p>
 <p>
 the strain of the structure part to the FBG and then the FBG measures 
 the strain to obtain the curvature.
 </p>
 <p>
 The performed simulation and experiment show that the sensor can 
 effectively amplify the strain to the
 </p>
 <p>
 FBG through the unique structure of the elastomer, and the accuracy of 
 the sensor used in the experiment is
 </p>
 <p>
 increased by 14% compared with that of the FBG used for direct 
 measurement.
