摘　　要：热衰竭是消防员常见的一种病症,主要表现为人体体液和电解质的大量丢失,导致周围血管循环机能衰竭,进而危及生命。本文设计了一种基于汗液分析的多通道电化学传感织物,研究了pH、钠离子、钾离子3种传感纤维的制备方法,分析了其对汗液成分的传感性能。结果表明,基于纤维材料的pH、钠离子、钾离子传感器均表现出良好的灵敏度、线性度及抗干扰性。其中,pH传感纤维的灵敏度为53.33 mV·pH^(-1),钠离子传感纤维的灵敏度为30.83 mV·dec^(-1),钾离子传感纤维的灵敏度为38.58 mV·dec^(-1),为预防消防员热衰竭提供了有效保证。Heat exhaustion is a common disease of firefighters,mainly manifested by the loss of body fluids and electrolytes,leading to the failure of peripheral vascular circulation,and then life‒threatening.In this work,a multi‒channel electrochemical sweat sensing fabric was designed.The preparation methods of pH,sodium ion and potassium ion sensor fibers were studied,and their sensing properties to sweat components were analyzed.The results show that the pH,sodium ion and potassium ion sensors based on fiber materials show good sensitivity,linearity and anti‒interference.Among them,the sensitivity of pH sensor fiber is 53.33 mV pH^(‒1),the sensitivity of sodium ion sensor fiber is 30.83 mV dec^(‒1),and the sensitivity of potassium ion sensor fiber is 49.16 mV dec^(‒1),which provides an effective guarantee for preventing heat exhaustion.
