Title: | Highly stretchable hybrid silica/polymer optical fiber sensors for large-strain and high-temperature application | Authors: | Liu, Y Yu, CY |
Issue Date: | 2019 | Source: | Optics express, 22 July 2019, v. 27, no. 15, p. 20107-20116 | Abstract: | The large-range and high-sensitivity strain measurement in high-temperature ambiance is a great challenge in engineering applications. Because of the frangibility of the glass material, the traditional optical fiber strain sensors cannot endure a limit strain of 1%. To break through the limit, we propose a hybrid silica/polymer optical fiber sensor. It can endure extraordinarily large strain. The maximum strain of 35% is confirmed by experiments. To achieve high sensitivity and detect a small change in strain, a phase tracking method is used. The sensitivity of the sensor is 28 pm/mu epsilon which is 28 times larger than that of the traditional FBG sensors. In addition, because of the excellent high-temperature endurance of polyimide (PI) and adhesive, the sensor can survive in the high temperature up to 220 degrees C. The proposed hybrid silica/polymer optical fiber sensor has potentials to monitor deformation in plastic products, structure health in composite materials, and even strain in biomaterials. | Publisher: | Optical Society of America | Journal: | Optics express | EISSN: | 1094-4087 | DOI: | 10.1364/OE.27.020107 | Rights: | © 2019 Optical Society of America under the terms of the OSA Open Access Publishing Agreement (https://www.osapublishing.org/library/license_v1.cfm#VOR-OA) © 2019 Optical Society of America.
