Submerged systems are found in many engineering, biological, and medicinal applications. For such systems, due to the particular environmental conditions and working medium, the research on the mechanical and structural properties at every scale (from macroscopic to nanoscopic), and the control of the system dynamics and induced effects become very difficult tasks. For such purposes in submerged systems, piezoelectric patches (PZTp), which are light, small and economic, have been proved to be a very good solution. PZTp have been recently used as sensors/actuators for applications such as modal analysis, active sound and vibration control, energy harvesting and atomic force microscopes in submerged systems. As a consequence, in these applications, newly developed transducers based on PZTp have become the most used ones, which has improved the state of the art and methods used in these fields. This review paper carefully analyzes and summarizes these applications particularized to submerged structures and shows the most relevant results and findings, which have been obtained thanks to the use of PZTp.
浸没系统在许多工程、生物和医学应用中都有发现。对于此类系统，由于特殊的环境条件和工作介质，对各尺度（从宏观到纳米级）的机械和结构特性的研究以及对系统动力学和诱导效应的控制都变得非常困难。对于浸没系统中的此类目的，压电贴片（PZTp）已被证明是一种非常好的解决方案。PZTp 最近已被用作传感器/执行器，用于模态分析、主动声和振动控制、能量收集和浸没系统中的原子力显微镜等应用。因此，在这些应用中，基于 PZTp 的新型换能器已成为最常用的换能器，这提高了这些领域使用的技术和方法的水平。本文仔细分析和总结了这些特别针对浸没结构的应用，并展示了由于使用 PZTp 而获得的最相关结果和发现。
