Fiber electronics with flexible and weavable features can be easily integrated into textiles for wearable applications. However, due to small sizes and curved surfaces of fiber materials, it remains challenging to load robust active layers, thus hindering production of high-sensitivity fiber strain sensors. Herein, functional sensing materials are firmly anchored on the fiber surface in-situ through a hydrolytic condensation *** anchoring sensing layer with robust interfacial adhesion is ultra-mechanically sensitive, which significantly improves the sensitivity of strain sensors due to the easy generation of microcracks during stretching. The resulting stretchable fiber sensors simultaneously possess an ultra-low strain detection limit of 0.05%, a high stretchability of 100%, and a high gauge factor of 433.6, giving 254-folds enhancement in sensitivity. Additionally, these fiber sensors are soft and lightweight, enabling them to be attached onto skin or woven into clothes for recording physiological signals, e.g. pulse wave velocity has been effectively obtained by them. As a demonstration, a fiber sensor-based wearable smart healthcare system is designed to monitor and transmit health status for timely intervention. This work presents an effective strategy for developing high-performance fiber strain sensors as well as other stretchable electronic devices.

建筑节能对实现“双碳”战略目标有重要影响。为进一步提升建筑柔性用能潜力及自动化管理水平,亟需构建融合物联网、大数据等信息化技术的通用性建筑运维技术。本文提出了1种面向中央空调系统的柔性优化控制方法,通过数据驱动方式构建系统能效及功能模型,进而从用能效率及成本层面实现优化控制。主要方法逻辑如下:首先,构建高精度建筑负荷预测模型,结合分时电价优化供冷量分布,节约用能成本;其次,构建中央空调系统关键设备能效及功能模型,包括制冷机组、各类水泵及冷却塔等,以推演不同工况下的运行表现;最后,基于启发式算法优化逐时控制参数,在满足负荷需求的前提下提升运行效率。以深圳市某酒店建筑为例,本文提出的柔性优化控制方法可有效调动建筑系统柔性潜力,节能和节财率分别达到19.1%和22.8%。相关研究成果有望为建筑系统柔性管理提供新思路和新参考。
