本文设计了一种新型的用于呼吸运动分析的周期性宏弯曲异芯光纤传感器。我们报告了几种不同的设计的基础上，纺织品具有不同的循环周期和配置的光纤类型。在所有实验中，在呼吸运动期间测量织物伸长率的变化。为了验证该传感器的优越性，对62.5 - 50 - 62.5 μ m异芯光纤构成的宏弯曲传感器和62.5/125 μ m多模光纤构成的不同环的宏弯曲传感器进行了实验研究。实验结果表明，所提出的宏弯曲传感器构造使用异芯光纤的灵敏度是远远高于由普通多模光纤构造的传感器。它还表明，传感器的灵敏度增加的环路的数量增加。另一方面，通过改变环幅值和周期的长度，对具有不同弯曲半径的周期性宏弯曲传感器进行了实验。我们证明了在不同患者形态上测试的传感器可以成功地感知呼吸运动。
This paper presents the design of a novel periodic macrobending hetero-core fiber optic sensor embedded in textile for respiratory movements’ analysis. We report on several different designs based on textiles which have different loop periodicity and configuration of optical fiber types. In all experiments, the changes of textile elongation are measured during breathing movements. In order to demonstrate the superiority of the proposed sensor, experiments were done on a macrobending sensor constructed from 62.5-50-62.5 hetero-core fiber and a macrobending sensor constructed from 62.5/125 μm multi-mode fiber having different loops. Experimental results show that the sensitivity of the proposed macrobending sensor constructed using hetero-core optical fiber is much higher than the sensor constructed from plain multi-mode optical fiber. It is also shown that, the sensitivity of the sensor increases as the number of loops is increased. On the other hand, several experiments were performed for periodic macrobending sensors having different bending radius by changing the lengths of loops amplitude and period. We demonstrate that the sensors tested on different patients’ morphology can successfully sense respiratory movements.
