舒适且易于佩戴的智能纺织品在持续呼吸监测中广受欢迎。在不同的新兴技术中，基于光纤传感器（FOS）的智能纺织品具有多种优势，例如磁共振（MR）兼容性和良好的计量性能。在本文中，我们报告了基于 FOS 的用于呼吸监测的 MR 兼容智能纺织品的开发和评估。该系统由粘在纺织品上的六个光纤布拉格光栅 (FBG) 传感器组成，用于监测胸壁的六个隔室（即右上胸部和左上胸部、右腹部肋骨和左腹部肋骨以及右腹部和左腹部）。该解决方案可以监测全局呼吸参数和每个隔室容积变化。该系统将胸部运动转换为光纤光栅测量的应变。通过使用光电系统进行的实验优化了光纤光栅的定位。智能纺织品的可行性在 6 名健康志愿者身上进行了评估。将实验数据与用作参考的光电体积描记法估计的数据进行比较。在呼吸期（最大百分比误差为 1.14%）、吸气期和呼气期以及总容量变化（两个系统之间的平均百分比差异约为 14%）方面均获得了有希望的结果。 Bland-Altman 分析显示所研究的参数具有令人满意的准确性。所提出的系统是安全的、非侵入性的、MR兼容的，并且允许监测隔室体积。
Comfortable and easy to wear smart textiles have gained popularity for continuous respiratory monitoring. Among different emerging technologies, smart textiles based on fiber optic sensors (FOSs) have several advantages, like Magnetic Resonance (MR)-compatibility and good metrological properties. In this paper we report on the development and assessment of an MR-compatible smart textiles based on FOSs for respiratory monitoring. The system consists of six fiber Bragg grating (FBG) sensors glued on the textile to monitor six compartments of the chest wall (i.e., right and left upper thorax, right and left abdominal rib cage, and right and left abdomen). This solution allows monitoring both global respiratory parameters and each compartment volume change. The system converts thoracic movements into strain measured by the FBGs. The positioning of the FBGs was optimized by experiments performed using an optoelectronic system. The feasibility of the smart textile was assessed on 6 healthy volunteers. Experimental data were compared to the ones estimated by an optoelectronic plethysmography used as reference. Promising results were obtained on both breathing period (maximum percentage error is 1.14%), inspiratory and expiratory period, as well as on total volume change (mean percentage difference between the two systems was ~14%). The Bland-Altman analysis shows a satisfactory accuracy for the parameters under investigation. The proposed system is safe and non-invasive, MR-compatible, and allows monitoring compartmental volumes.
