摘　　要：人体汗液富含丰富的与身体健康状况相关的电解质,采用可穿戴电化学离子传感器对汗液实时监测可为身体健康提供合理的指导.基于全固态离子选择性电极的可穿戴电化学传感器因能够实时无创地分析生物体液离子受到越来越多的关注.开发新的固接层材料,探索新的电位响应机理及在可穿戴设备上的应用促进了全固态离子选择性电极的发展.本文综述了全固态离子选择性电极的研究进展,包括传统的电位响应机理(氧化还原电容和双电层电容原理)和新型固接层材料(导电聚合物、碳和其他纳米材料)以及在可穿戴柔性传感器方面的应用.最后对全固态离子选择性电极存在的挑战和未来的前景做出了展望.Human sweat is rich in health-related electrolytes,so using wearable ion sensor to monitor sweat in real-time can provide reasonable guidance for people's health.Wearable electrochemical sensors based on all-solid-state ionselective electrodes have attracted more and more attention for their real-time non-invasive analysis of biological liquid ions on the body.The development of all-solid-state ion-selective electrodes has been promoted by the emerging of new solid contact layer materials,the exploration of novel potential response mechanism and the application in wearable devices.In this article,the research progress of all-solid-state ion-selective electrodes is reviewed,including potential response mechanism(redox capacitance and double-layer capacitance principle),solid contact layer materials(conductive polymers,carbon and other nanomaterials)and the application of wearable sensors.Finally,this review provides the challenges and future prospects of all-solid-state ion selective electrodes.
