摘要：
我们介绍了一种新型可穿戴纺织服装，其采用创新电极放置方式，旨在最大限度降低噪声和运动伪影，从而提高心电图（ECG）记录中的信号保真度。我们提出了一项全面、性别平衡的评估，涉及15名健康男性和15名健康女性参与者，以确保该设备适用于不同解剖和生理差异。该评估框架包含多种不同评价方法：用于客观基准化设备性能的定量信号质量指数；对心率和心率变异性等生理参数进行基于节律的分析；用于评估与应用相关的预测效用的机器学习分类任务；对包括振幅和间期参数在内的 ECG 特征进行形态学分析；以及研究由纺织物/身体形状决定的电极投影角度的影响；所有分析均按性别分层，以阐明性别特异性影响。评估在代表真实世界条件的各种活动阶段中进行。结果表明，该纺织系统在节律和形态学分析中均实现了与参考设备高度一致的信号质量，表现出稳健的分类性能，并能够识别影响信号采集的关键性别特异性决定因素。这些发现强调了基于纺织物的 ECG 服装在生理监测以及心理生理状态检测方面的实际可行性。此外，我们指出纳入性别特异性设计考虑对于确保可穿戴健康技术中公平、可靠的心脏诊断具有重要意义。
英文摘要：
We introduce a novel wearable textile-garment featuring an innovative electrode placement aimed at minimizing noise and motion artifacts, thereby enhancing signal fidelity in Electrocardiography (ECG) recordings. We present a comprehensive, sex-balanced evaluation involving 15 healthy males and 15 healthy female participants to ensure the device's suitability across anatomical and physiological variations. The assessment framework encompasses distinct evaluation approaches: quantitative signal quality indices to objectively benchmark device performance; rhythm-based analyzes of physiological parameters such as heart rate and heart rate variability; machine learning classification tasks to assess application-relevant predictive utility; morphological analysis of ECG features including amplitude and interval parameters; and investigations of the effects of electrode projection angle given by the textile / body shape, with all analyzes stratified by sex to elucidate sex-specific influences. Evaluations were conducted across various activity phases representing real-world conditions. The results demonstrate that the textile system achieves signal quality highly concordant with reference devices in both rhythm and morphological analyses, exhibits robust classification performance, and enables identification of key sex-specific determinants affecting signal acquisition. These findings underscore the practical viability of textile-based ECG garments for physiological monitoring as well as psychophysiological state detection. Moreover, we identify the importance of incorporating sex-specific design considerations to ensure equitable and reliable cardiac diagnostics in wearable health technologies.
