摘要： 海洋水文信息对发展和海洋资源探测具有重大作用，温盐深是海洋水文的基本要素。在海洋资源开发与利用中，海洋温盐深数据信息监测具有重要意义。CTD传感器是海水温盐剖面观测的主要仪器，利用CTD传感器可实现对不同深度海水的温度和电导率等参数的测量。近年来，凭借其出色的可拉伸、易贴附等优点，柔性电子传感器既在一定程度上实现了传统刚性传感器的传感性能，又弥补了传统传感器体积、重量大等缺陷，展示出巨大的应用潜力。本文综述了近年来柔性海洋CTD传感器的研究进展，主要包括柔性传感器的工作机理与分类、常用材料、制作工艺，并对现有的柔性海洋CTD传感器的结构、性能和应用平台进行了分析。最后，展望了柔性海洋CTD传感器的发展。

Abstract: Marine hydrological information plays a significant role in development and exploration of marine resources. Temperature, salinity and depth are fundamental elements of marine hydrology. Monitoring of marine temperature, salinity and depth data plays an important role in the development and utilization of marine resources. The conductivity temperature depth profiler (CTD) is the main instrument for observing seawater temperature and salinity profiles. By using CTD sensors, parameters such as temperature and conductivity of seawater at different depths can be measured. In recent years, flexible electronic sensors have demonstrated great potential for application due to their excellent stretchability and easy attachment, which not only achieve the sensing performance of traditional rigid sensors to a certain extent, but also compensate for the shortcomings of traditional sensors such as large volume and weight. This review introduces the research progress of flexible ocean CTD sensors in recent years, mainly including the working mechanism and classification, common materials, manufacturing processes of flexible sensors, and analyzes the structure, performance, and application platform of existing flexible ocean CTD sensors. Finally, the development of flexible ocean CTD sensors is prospected.

Key words: flexible sensor, CTD sensors, depth measurement, temperature measurement, salinity measurement
