|Keywords:||Bragg gratings;Temperature;Optical fibers;Fiber optics||Category:||Electrical Engineering - Electronic Engineering - Information Engineering||Field:||Engineering and Technology||Issue Date:||Sep-2010||Publisher:||Iop Science||Source:||Measurement Science and Technology, 2010, vol.21, no.9||Journal:||Measurement Science and Technology||Abstract:||We report on a Bragg grating written in an eccentric-cored polymer optical fibre for measurement of strain, bend and temperature. The strain sensitivity achieves 1.13 pm με -1. The temperature response shows a negative sign with the thermal sensitivity of -50.1 pm °C -1. For bend sensing, this device exhibits a strong fibre orientational dependence, wide bend curvature range of ±22.7 m -1 and a high bend sensitivity of 63.3 pm/m -1.||ISSN:||0957-0233 (print)
