Abstract

Smart textiles with high sensitivity and rapid response for various external stimuli have gained tremendous attentions in human healthcare monitoring, personal heat management, and wearable electronics. However, the current smart textiles only acquire desired signal passively, regularly lacking subsequent on-demand therapy actively. Herein, a robust, breathable, and flexible smart textiles as multi-function sensor and wearable heater for human health monitoring and gentle thermotherapy in real time is constructed. The composite fiber as strain sensor (CFY@PU) was fabricated via warping carbon fiber yarns (CFY) onto polyurethane fibers (PU), which endowed composite fiber with high conductivity, excellent sensitivity (GF = 76.2), and fantastic dynamic durability (7500 cycles) in strain sensing. In addition, CFY@PU can detect various degrees of human movements such as elbow bending, swallowing and pulse, which can provide effective information for disease diagnosis. More surprisingly, weaving CFY@PU into a fabric can assemble highly sensitive pressure sensor for remote communication and information encryption. Warping CFY onto Kevlar would obtain temperature-sensitive composite fiber (CFY@Kevlar) as temperature sensor and wearable heater for on-demand thermotherapy, which provided unique opportunities in designing smart textiles with ultrahigh sensitivity, rapid response, and great dynamic durability.

坚固、透气、灵活的智能纺织品作为个人健康管理的多功能传感器和加热器

智能纺织品具有对各种外界刺激的高灵敏度和快速响应能力，在人体健康监测、个人热管理和可穿戴电子产品等领域受到广泛关注。然而，目前的智能纺织品只是被动地获取所需的信号，通常缺乏主动的后续按需治疗。在此基础上，构建了一种坚固、透气、柔性的智能纺织品，作为多功能传感器和可穿戴加热器，用于人体健康监测和实时温和热疗。该复合纤维作为应变传感器(CFY@PU)通过将碳纤维纱(CFY)经翘曲加工到聚氨酯纤维(PU)上，使复合纤维具有高导电性、优异的灵敏度(GF = 76.2)和优异的动态耐久性(7500次)。此外，CFY@PU可以检测肘部弯曲、吞咽、脉搏等不同程度的人体运动，可以为疾病诊断提供有效的信息。更令人惊讶的是，将CFY@PU编织到织物中可以组装高灵敏度的压力传感器，用于远程通信和信息加密。将CFY翘曲到凯夫拉尔纤维上，可以得到温度敏感的复合纤维(CFY@Kevlar)作为温度传感器和可穿戴加热器，用于按需热疗，这为设计超高灵敏度、快速响应和高动态耐久性的智能纺织品提供了独特的机会。图形抽象
