摘要

通过将光纤布拉格光栅径向安装在环形弹性元件上,设计并制作了一种新型的大应变传感器。该传感器通过几何变形单向响应应变,应变测量范围大,灵敏度可调。这解决了现有FBG应变传感器的缺点,如易碎性、应变测量范围有限,以及适应各种应用和安装场景的挑战。实验表明,当光纤光栅与应变轴夹角为40°时,传感器的应变测量范围为0 - $12~148~\mu \varepsilon $,灵敏度为0.151 pm/ $\mu \varepsilon $。通过调整角度可以进一步调整传感器的性能。例如,在角度为30°、20°和10°时,灵敏度分别提高到0.506、0.858和1.035 pm/ $\mu \varepsilon $。这种灵活性允许定制灵敏度和测量范围,以满足各种应用需求。

Fiber Bragg Grating Strain Sensor With Extended Measurement Range via Strain Relief Ring
A novel large strain sensor is designed and fabricated by radially mounting a fiber Bragg grating (FBG) onto an annular elastic element. The sensor responds to strain in a single direction through geometric deformation, featuring a large strain measurement range and adjustable sensitivity. This addresses the drawbacks of existing FBG strain sensors, such as fragility, limited strain measurement range, and challenges in adapting to diverse applications and installation scenarios. Our experiments demonstrate that at an angle of 40° between the FBG and the strain axis, the sensor achieves an impressive strain measurement range of 0– $12~148~\mu \varepsilon $ accompanied by a sensitivity of 0.151 pm/ $\mu \varepsilon $ . The sensor’s performance can be further tailored by adjusting the angle. For instance, at angles of 30°, 20°, and 10°, the sensitivities are enhanced to 0.506, 0.858, and 1.035 pm/ $\mu \varepsilon $ , respectively. This flexibility allows for customized sensitivity and measurement range, catering to various application needs.
