摘　　要：针对我国未来载人航天任务需求,开展可用于航天员长期在轨心电信号采集的织物电极技术分析。首先,对传统Ag/Ag Cl胶状电极在长期心电监测应用中遇到的问题进行了讨论。其次,介绍了干电极的概念、种类以及发展现状,分析了不同类型干电极的技术特点。再次,结合我国载人航天任务特点,对不同类型干电极的适用性进行比较,得出织物电极是一种适合航天员长期在轨监测的心电传感器的结论,它具有舒适性、可穿戴性、可水洗性、稳定性、易集成性等显著特点。最后,针对织物电极技术需要突破的关键技术进行了总结和展望。According to the requirements of the future manned spaceflight missions in China,textile electrode technologies applicable to long-term electrocardiogram（ ECG） acquisition on orbit for astronauts were analyzed in this paper. Firstly,some problems in long-term monitoring of ECG signal using Ag / Ag Cl gelled electrodes were discussed. Secondly,the concept,type,and the development status of dry electrodes were introduced,and the technical characteristics of various types of dry electrodes were analyzed. Then,based on China＇s manned space missions,the applicability of various types of dry electrodes was compared. It was found that the textile electrode,which was comfortable,wearable,washable,stable and integratable,was suitable for long-term ECG monitoring on orbit of astronauts. Finally,some key technologies of the textile electrodes were summarized and prospected.
