Etched Polymer Fibre Bragg Gratings and Their Biomedical Sensing Applications.
Sensors, 2017Co-Authors: Ginu Rajan, Kishore Bhowmik, Jiangtao Xi, Gang-ding PengAbstract:Bragg gratings in etched Polymer Fibres and their unique properties and characteristics are discussed in this paper. Due to the change in material and mechanical properties of the Polymer Fibre through etching, Bragg gratings inscribed in such Fibres show high reflectivity and enhanced intrinsic sensitivity towards strain, temperature, and pressure. The short-term and long-term stability of the gratings and the effect of hysteresis on the dynamic characteristics are also discussed. The unique properties and enhanced intrinsic sensitivity of etched Polymer Fibre Bragg grating are ideal for the development of high-sensitivity sensors for biomedical applications. To demonstrate their biomedical sensing capabilities, a high-sensitivity pressure transducer that operates in the blood pressure range, and a breathing rate monitoring device are developed and presented.

High-sensitivity Polymer Fibre Bragg grating sensor for biomedical applications
2016 IEEE Sensors Applications Symposium (SAS), 2016Co-Authors: Kishore Bhowmik, Eliathamby Ambikairajah, Gang-ding Peng, Yanhua Luo, Ginu RajanAbstract:Single-mode Polymer optical Fibre Bragg gratings (POFBGs) are etched to different diameters and their potential for the development of high-sensitivity sensors are presented. The material properties of the Fibre can be changed by etching and thus the etching procedure can have an impact on the performance of POFBGs. To confirm that the material properties of etched Polymer Fibre can be modified and its sensitivity enhanced, sensing characteristics of different etched POFBGs for pressure, strain and temperature are investigated. From the experimental results, we show that the sensors based on etched Polymer Fibres exhibit a higher sensitivity and they are more desirable than the un-etched ones for biomedical applications. Two examples of low pressure sensor such as blood pressure sensor and foot pressure sensor are demonstrated. With etching, enhanced sensitivity and bio-compatible Polymer Fibre sensors could be very useful for biomedical applications.

Wavelength tuning of Polymer optical Fibre Bragg grating at longer wavelengths permanently
Third International Conference on Applications of Optics and Photonics, 2017Co-Authors: Georgios Sagias, Andreas Pospori, Daniel Gallego, David J. Webb, Horacio Lamela RiveraAbstract:Permanent Bragg wavelength tuning of Polymer optical Fibre Bragg grating (POFBG) at longer wavelengths has been demonstrated for the first time utilising the thermal annealing process. In general, exposing the Polymer material above its β-Transition temperature, the Fibre shrinks in length, the Bragg grating period becomes shorter and the Bragg wavelength shifts permanently to shorter wavelengths. In this work, a positive tuning of Bragg wavelength has been shown to be feasible when the Polymer Fibre is stretched during its thermal exposure. The results show that the degree of Bragg wavelength tuning strongly depends on the applying Fibre strain or equivalently stress. The work presented in this paper can be used to multiplex POFBGs at any desirable wavelength.

embedding silica and Polymer Fibre bragg gratings fbg in plastic 3d printed sensing patches
Proceedings of SPIE, 2016Co-Authors: Michal Zubel, David J. Webb, Kate Sugden, D Saezrodriguez, Kristian Fog Nielsen, Ole BangAbstract:This paper reports the first demonstration of a silica Fibre Bragg grating (SOFBG) embedded in an FDM 3-D printed housing to yield a dual grating temperature-compensated strain sensor. We also report the first ever integration of Polymer Fibre Bragg grating (POFBG) within a 3-D printed sensing patch for strain or temperature sensing. The cyclic strain performance and temperature characteristics of both devices are examined and discussed. The strain sensitivities of the sensing patches were 0.40 and 0.95 pm/μϵ for SOFBG embedded in ABS, 0.38 pm/μμ for POFBG in PLA, and 0.15 pm/μμ for POFBG in ABS. The strain response was linear above a threshold and repeatable. The temperature sensitivity of the SOFBG sensing patch was found to be up to 169 pm/°C, which was up to 17 times higher than for an unembedded silica grating. Unstable temperature response POFBG embedded in PLA was reported, with temperature sensitivity values varying between 30 and 40 pm/°C.

Polymer Fibre Bragg gratings and sensing
Sensors, 2015Co-Authors: Gang-ding Peng, Kishore Bhowmik, Eliathamby Ambikairajah, Ginu Rajan, David J. WebbAbstract:Polymer FBGs have advantages for sensing because of low Young's modulus, high temperature sensitivity, large strain range and so on. They are attractive for many niche applications such as structural health monitoring of composite materials, biochemical and biomedical sensing. While Polymer FBGs have been developed for some time, Polymer microFibre Bragg gratings are developed only recently and have shown to introduce some interesting features, e.g. increased pressure sensitivity to pressure / force and improved response time to humidity. We will report and discuss the recent work on Polymer FBG and Polymer microFibre Bragg gratings as well as their applications such as accelerometer, humidity sensor and force and pressure sensor. © 2015 OSA.
