具有高灵敏度和对各种外部刺激快速响应的智能纺织品在人类健康监测、个人热量管理和可穿戴电子产品中获得了极大的关注。然而，目前的智能纺织品只是被动地获取所需信号，往往缺乏后续的主动按需治疗。本文构建了一种坚固、透气且灵活的智能纺织品，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。通过将碳纤维纱（CFY）整经到聚氨酯纤维（PU）上制备了复合纤维作为应变传感器（CFY @PU），这使得复合纤维在应变传感中具有高导电性、优异的灵敏度（GF = 76.2）和出色的动态耐久性（7500次循环）。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压力传感器，用于远程通信和信息加密。将CFY翘曲到Kevlar上将获得温度敏感复合纤维（CFY @Kevlar）作为温度传感器和用于按需热疗的可穿戴加热器，这为设计具有超高灵敏度、快速响应和出色动态耐久性的智能纺织品提供了独特的机会。
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.
