An ultra-sensitive contact force sensor based on a polymerized hollow-cylinder lying on the end-face of single-mode fiber is proposed. The whole hollow-cylinder is polymerized in a single illumination with an annular beam, which is generated by a section of multimode fiber without resorting to any expensive instruments. It is fixed on the end-face of the fiber with UV-glue, working as a Fabry-Perot cavity. Owing to both the hollow structure and the low Young’s modulus of polymer, experimental results show the contact force sensitivity of the sensor reaches as high as 1.08 nm / μN\mu \text{N} , and the detection resolution of the sensor is 0.2 μN0.2~\mu \text{N} .

一种基于聚合空心圆柱的一步制作的微牛顿接触力超灵敏光纤传感器



提出了一种基于单模光纤端面聚合空心圆柱体的超灵敏接触力传感器。整个空心圆柱体在具有环形光束的单次照明中聚合,该环形光束由一段多模光纤产生,无需借助任何昂贵的仪器。它用UV胶固定在光纤端面上,起到法布里-珀罗腔的作用。由于聚合物的中空结构和低杨氏模量,实验结果表明传感器的接触力灵敏度高达1.08 nm / μN\mu \text{N} ,传感器的检测分辨率为0.2 μN0 .2~\mu \text{N} .
