Abstract

Background and Objectives: Nonintrusive heart rate (HR) monitoring can be a useful tool for health monitoring. By creating capacitively coupled textile electrodes, a comfortable monitoring system can be integrated into seating or bedding that can monitor HR through clothing. This work empirically studied two factors for a system of this type: the electrode size and the material worn by the subject. Materials and Methods: HR measurements were taken using six different sizes of the rectangular textile electrode with four subjects and the signal-to-noise ratio (SNR) of the signals were analyzed. A further set of experiments were conducted with a single subject and a fixed electrode size where different materials were worn. Results: Electrode size was seen to have a statistically insignificant effect on the collected signal quality. The SNR was also largely unaffected by the worn material type. Conclusion: This study provided empirical data relating to two important factors for nonintrusive, textile, and HR monitoring systems. This data will be helpful for designing a seat-based HR monitoring system or to understand the operational limitations of a system of this type.
了解非侵入式纺织心率监测系统的设计规则
背景和目的:非侵入性心率(HR)监测可以成为健康监测的有用工具。通过创建电容耦合的纺织品电极,可以将舒适的监测系统集成到座椅或床上用品中,通过衣服监测HR。这项工作对这种类型的系统的两个因素进行了实证研究:电极尺寸和受试者佩戴的材料。材料和方法:对四名受试者使用六种不同尺寸的矩形织物电极进行HR测量,并分析信号的信噪比。在佩戴不同材料的情况下,对单个受试者和固定电极尺寸进行了另一组实验。结果:电极尺寸对采集的信号质量的影响在统计学上不显著。SNR在很大程度上也不受磨损材料类型的影响。结论:本研究提供了与非侵入性、纺织和人力资源监测系统两个重要因素相关的经验数据。这些数据将有助于设计基于座位的人力资源监控系统或了解此类系统的操作限制。
