By fusing wearable sweat sensors for on-body sweat monitoring with textiles for daily wear, wearable textile sweat sensors (WTSSs) demonstrate the distinctive capability to monitor perspiration in real time while engaging in daily activities. However, previous WTSSs mainly focused on "weave-in-textile" or "print-on-textile" ones, which are permanently immobilized on specific regions of specific types of textiles prior to use and, accordingly, cannot be used in some specific routine circumstances (e.g., temporary changes in textile type/immobilization region). Here, in an alternative "stick-to-textile" approach, the first example of a single carbon microyarn-based integrated WTSS that is built into a hook-and-loop fastener (SI@HLF) for on-body, dynamic, and multiplexed sweat monitoring is reported. This system integrates a surface-engineered, loop-based antigravity transport module for directional sweat transport; a single carbon microyarn-based sensing array module for sweat biomarker analysis; a printed circuit board (PCB)-based data processing module for monitoring and control; and an adhesive module based on a patterned adhesive film on the loop for universal immobilization. We tested the performance of SI@HLF in healthy subjects under controlled trials simulating daily exercise. We also evaluated the utility of SI@HLF when immobilized on various types of textiles and textile regions during routine activities.
通过将用于人体汗液监测的可穿戴汗液传感器与日常穿着的纺织品相结合，可穿戴纺织汗液传感器（WTSS）展现出在日常活动中实时监测排汗情况的独特能力。然而，以往的WTSS主要集中在“织入纺织品”或“印在纺织品上”的类型，这些在使用前就永久固定在特定类型纺织品的特定区域，因此无法在某些特定日常情况下使用（例如，纺织品类型/固定区域的临时变化）。在此，采用一种替代性的“粘贴到纺织品”方法，报道了首个基于单根碳微纱的集成式WTSS实例，该传感器集成在用于人体、动态和多重汗液监测的钩环扣（SI@HLF）中。该系统集成了一个用于定向汗液传输的表面工程化、基于毛圈的反重力传输模块；一个用于汗液生物标志物分析的基于单根碳微纱的传感阵列模块；一个用于监测和控制的基于印刷电路板（PCB）的数据处理模块；以及一个基于毛圈上图案化胶膜的用于通用固定的粘合模块。我们在模拟日常锻炼的对照试验中测试了SI@HLF在健康受试者中的性能。我们还评估了SI@HLF在日常活动中固定在各种类型纺织品和纺织区域时的实用性。
