Abstract

Heat exhaustion is a prevalent heat-related illness among firefighters, posing a severe threat to life without timely intervention. However, current firefighter garments are limited by their singular functionality and cannot collect or analyze body fluid during rescue missions. Here, we introduce a wetting gradient effect assisted ultrasensitive meta-garment that incorporates multi-signal biomonitoring, offering an early warning system for heat exhaustion risk. This design enables real-time detection of heart rate, pH value, and the concentrations of glucose, sodium, and potassium in sweat. Benefiting from the surface energy difference, gradient wettability surfaces can be formed, allowing for precise point-to-point fluid control and regulation. Thus, the biosensing fibers require the lowest detection volume (0.1 μL) and fastest response time (1.4 s) reported to date. This innovative garment provides a practical solution for early health warning based on abnormal multi-biomarker changes, representing a significant advancement in firefighter safety.

基于湿梯度效应的超灵敏生物传感超衣热衰竭预警

中暑衰竭是消防员中普遍存在的与热有关的疾病，如果不及时干预，会对生命构成严重威胁。然而，目前的消防员服装受到其单一功能的限制，无法在救援任务中收集或分析体液。在这里，我们介绍了一种湿梯度效应辅助的超灵敏超敏衣，它结合了多信号生物监测，为热衰竭风险提供了一个早期预警系统。这种设计可以实时检测心率、pH值以及汗液中葡萄糖、钠和钾的浓度。得益于表面能差，可以形成梯度润湿性表面，从而实现精确的点对点流体控制和调节。因此，生物传感纤维需要最小的检测体积（0.1 μL）和最快的响应时间（1.4 s）。这种创新的服装为基于多种生物标志物异常变化的早期健康预警提供了实用的解决方案，代表了消防员安全的重大进步。
