生物生理信号的长期监测需要新型的可穿戴且方便用户使用的传感器系统。本文介绍了一种基于服装的呼吸节律长期监测传感系统的设计。该系统的概念是在一件原型服装中实现的，并集成了涂层压阻传感器。该原型衣由五名受试者进行了测试，并与标准的压电呼吸带进行了比较。在时域和频域对每个信号进行定量和定性评估，以确保不丢失医疗和诊断信息。结果显示，基于服装的传感器与标准参考之间的一致性很好，只有在呼吸频率极高时才会出现错误。基于服装的传感器系统还可以区分主要呼吸区（胸部呼吸和腹部呼吸）。该系统可以检测到呼吸暂停10秒，这对研究睡眠呼吸暂停很重要。基于服装的传感系统在不降低用户舒适度的情况下保持信号质量的准确性。它使长期动态监测成为可能，并具有基于家庭的医疗保健应用。
The long-term monitoring of biophysiological signals requires new types of sensor systems that are wearable and at the same time convenient for the users. This paper describes the design of a novel garment-based sensing system for the long-term monitoring of breathing rhythm. The system concept was realized in a prototype garment, integrated with coated piezoresistive sensors. The prototype garment was tested by five subjects, and compared with a standard piezoelectric respiratory belt. Each signal was quantitatively and qualitatively evaluated in the time and frequency domain to make sure that no medical and diagnostic information was lost. The results showed a good agreement between the garment-based sensors and the standard reference, where errors occurred only when the breathing rate was extremely high. The garment-based sensor system could also distinguish the predominance breathing compartment (chest versus abdominal breathing). The system could detect a 10 s pause in breathing, which could be of importance in studies of sleep apnea. A garment-based sensing system maintains the accuracy of the signal quality without reducing the comfort for the user. It makes possible long-term ambulatory monitoring and has home-based healthcare applications.
