在过去的几十年里，柔性传感器已经从“电子”水平发展到“离子”水平，并逐渐发展到“离子”水平。离子柔性传感器（IFS）是一种基于离子迁移原理的先进传感器。与传统的电子传感器相比，IFS不仅能够复制人体皮肤的拓扑结构，而且能够实现类似于人体皮肤的触觉感知功能，为缩小传统电子学与生物学接口之间的差距提供了有效的工具和方法。本文综述了IFS的几种典型传感机理、组成、结构设计和应用等方面的最新研究进展。特别是，新型离子材料、结构设计和仿生方法的发展已经导致了广泛的新颖和令人兴奋的IFS的发展，其可以以高灵敏度和可靠性有效地感测压力、应变和湿度，并表现出自供电、自修复、生物降解性和人类皮肤的其他特性。此外，IFS在人工皮肤，人机交互技术，可穿戴健康监测器，和其他相关领域的典型应用进行了审查。最后，对综合融资战略目前面临的挑战和未来的发展方向提出了看法。
Over the past few decades, flexible sensors have been developed from the “electronic” level to the “iontronic” level, and gradually to the “ionic” level. Ionic flexible sensors (IFS) are one kind of advanced sensors that are based on the concept of ion migration. Compared to conventional electronic sensors, IFS can not only replicate the topological structures of human skin, but also are capable of achieving tactile perception functions similar to that of human skin, which provide effective tools and methods for narrowing the gap between conventional electronics and biological interfaces. In this review, the latest research and developments on several typical sensing mechanisms, compositions, structural design, and applications of IFS are comprehensively reviewed. Particularly, the development of novel ionic materials, structural designs, and biomimetic approaches has resulted in the development of a wide range of novel and exciting IFS, which can effectively sense pressure, strain, and humidity with high sensitivity and reliability, and exhibit self‐powered, self‐healing, biodegradability, and other properties of the human skin. Furthermore, the typical applications of IFS in artificial skin, human‐interactive technologies, wearable health monitors, and other related fields are reviewed. Finally, the perspectives on the current challenges and future directions of IFS are presented.
