Abstract :
Fibre Bragg grating sensors have been success fully created in a recent commercial polymer optical fibre material. A team of researchers from the UK, Denmark and Cyprus report that they can reliably produce fibre Bragg grating (FBG) sensor structures in TOPAS cyclic olefin copolymer microstructured polymer optical fibre (POF). With a temperature response similar to poly (methyl methacrylate) (PMMA) and lower sensitivity to water, these sensors have potential for long-term temperature and strain monitoring.
