可穿戴子宫电描记系统：电极拓扑、设计考量与临床可行性的系统综述。
完整摘要 · 中文译文
子宫肌电图（EHG）是一种先进的无创技术，用于从母体腹壁表面表征子宫肌层活动。尽管其具有临床相关性，但EHG在可穿戴系统中的推广应用受到电极配置变异性和缺乏集成系统设计的阻碍。采用基于PRISMA 2020的系统综述方法，对1997年9月至2026年1月间的出版物进行了检索，检索数据库包括IEEE Xplore、PubMed、Semantic Scholar、ScienceDirect、SpringerLink、MDPI、IOP和Frontiers，并通过Publish or Perish进行Crossref检索补充，同时辅以手动引文追踪。在检索到的1084条记录中，有91篇出版物被纳入证据综合。分析考察了电极配置、可穿戴设计和测量方法，重点关注电极密度和位置对信号质量及临床可用性的影响。所综述的文献表明，采用约8-16个电极的配置代表了在空间表征与临床可用性之间取得平衡的实用范围。然而，研究结果揭示了与电极设计、信号采集和分析方法集成有限相关的持续挑战。这一证据强调了采用集成方法的必要性，该方法需考虑柔性电极接口、标准化电极配置和自适应信号处理技术。通过将技术进步与临床需求相结合，本研究为开发可穿戴母胎监护系统确定了实际考量因素。

Electrohysterography (EHG) is an advanced, noninvasive technique for characterizing myometrial activity from the maternal abdominal surface. Despite its clinical relevance, the adoption of EHG in wearable systems is hindered by variability in electrode configurations and a lack of integrated system design. A PRISMA 2020-based systematic review of publications from September 1997 to January 2026 was conducted using IEEE Xplore, PubMed, Semantic Scholar, ScienceDirect, SpringerLink, MDPI, IOP, and Frontiers, supplemented by Crossref searches via Publish or Perish and manual citation tracking. Of the 1084 records identified, 91 publications were included in the evidence synthesis. The analysis examined electrode configurations, wearable design, and measurement methodologies, focusing on the effects of electrode density and placement on signal quality and clinical usability. The reviewed literature indicates that configurations employing approximately 8-16 electrodes represent a practical range for balancing spatial characterization and clinical usability. However, the findings reveal persistent challenges related to the limited integration of electrode design, signal acquisition, and analytical methods. This evidence underscores the need for an integrated approach that considers flexible electrode interfaces, standardized electrode configurations, and adaptive signal processing techniques. By aligning technological improvements with clinical requirements, this study identifies practical considerations for developing wearable maternal-fetal monitoring systems.
