摘要

本文描述了一种用于传感目的的弹性体材料中光纤布拉格光栅封装的研究。在0到1500克的测量间隔内，对传感器施加的载荷所产生的力进行了测试。分析了弹性体成分对传感器响应的影响。结果指出了调整响应的可能性，以使传感器适应特定的应用。对传感器的灵敏度、线性度、滞回率和分辨率等计量特性进行了评价。有机硅弹性体道康宁®BX3-8001脱颖而出，因为它的硬度可以改变，也因为更短的固化时间，导致传感器的灵敏度为(0.312±0.002)pm/g，分辨率为(1.6±0.6)g，线性度为±4.19%，滞后率为±6.29%。

Fabrication and characterization of fiber Bragg grating based sensors for force measurements

This work describes a study about encapsulation of fiber Bragg gratings in elastomer materials for sensing purposes. Sensors were tested in measurements of forces resulting from loads applied to the sensor within a measuring interval from 0 to 1500 grams. It was analyzed the influence of the elastomer composition in the sensor response. Results point to the possibility of adjusting the responses in order to adequate the sensors for specific applications. Metrological characteristics were evaluated regarding the sensors sensitivity, linearity, hysteresis and resolution. The silicone elastomer DOW CORNING® BX3-8001 stood out due to the possibility of changing its hardness and also due to the lower cure time, resulting in a sensor with sensitivity of (0.312 ± 0.002) pm/g, resolution of (1.6 ± 0.6) g, linearity of ± 4.19 % and hysteresis of ± 6.29 %.
