Fabric has long‐term and the closest relationship to humans and is one of the measures of human progress and civilization. Functional fabrics are vigorously developed over the past few decades due to the explosive increase in portable electronic products. Fall detection is becoming increasingly important with the recent rapid aging of the population. Here, a pressure‐sensitive and large‐scale carpet for self‐powered fall detection, which is based on the textile‐triboelectric nanogenerators (t‐TENGs) arrays inlaid in common textile, is proposed. Core–shell yarns with conductive fibers as the core and common clothing fibers as the shell fabricated by a commercially available weaving method are used to constructed the smart t‐TENGs. The fabricated smart carpet exhibits desirable features including high sensitivity, fast response time, scalable production, comfortability, washability, and compatibility with existing home decoration. Furthermore, apart from highly integrated data acquisition and processing, arrangement of t‐TENGs cells and trigger algorithm are deliberately designed to effectively and simply realize real‐time and self‐powered falling behavior monitoring. Possessing these unique merits, the proposed system demonstrates great potential in more humanized medical healthcare systems and can be applied to innumerable families.

大型智能地毯，用于自供电跌倒检测

面料与人类有着长期和最密切的关系，是人类进步和文明的手段之一。由于便携式电子产品的爆炸性增长，功能性织物在过去的几十年中得到了蓬勃发展。随着人口的快速老龄化，跌倒检测变得越来越重要。在此，提出了一种压感大尺寸地毯，用于自动供电的跌倒检测，该地毯基于镶嵌在普通纺织品中的纺织品摩擦电动纳米发生器（t-TENGs）阵列。通过商业化的编织方法制造的以导电纤维为芯的核-壳纱线和普通的服装纤维为壳，可构造出智能t-TENG。制成的智能地毯展现出理想的功能，包括高灵敏度，快速响应时间，可扩展的生产，舒适性，可清洗性以及与现有家庭装饰的兼容性。此外，除了高度集成的数据采集和处理外，还特意设计了t-TENG单元的排列和触发算法，以有效，简单地实现实时和自供电的坠落行为监控。拥有这些独特的优点，所提出的系统在更加人性化的医疗保健系统中显示出巨大的潜力，并可以应用于无数家庭。
