This review article focuses on the latest achievements in the creation of a class of electrotuneable optical metamaterials for switchable mirrors/windows, variable colour mirrors, optical filters, and SERS sensors, based on the voltage-controlled self-assembly of plasmonic nanoparticles at liquid/liquid or solid/liquid electrochemical interfaces. Practically, these experimental systems were navigated by physical theory, the role of which was pivotal in defining the optimal conditions for their operation, but which itself was advanced in feedback with experiments. Progress and problems in the realisation of the demonstrated effects for building the corresponding devices are discussed. To put the main topic of the review in a wider perspective, the article also discusses a few other types of electrovariable metamaterials, as well as some of those that are controlled by chemistry.

电化学光子学：通往电变光学超材料的途径

这篇评论文章重点介绍了基于液体/等离子体纳米粒子的电压控制自组装，为可切换镜子/窗口、可变颜色镜子、滤光片和 SERS 传感器创建一类电调光学超材料的最新成果。液体或固体/液体电化学界面。实际上，这些实验系统是由物理理论引导的，物理理论在定义最佳操作条件方面起着关键作用，但它本身在实验反馈中得到了推进。讨论了构建相应器件的演示效果实现的进展和问题。为了从更广阔的视角来探讨本综述的主题，本文还讨论了其他几种电变超材料，
