In this review paper, we mainly focus on applications where the hydrostatic pressure is low and thin PZT transducers (also known as PZT patches) are used independently or attached to the submerged structure.

2018年8月1日 · PZT patches are increasingly being used in health monitoring schemes and in developing damage detection strategies for structural components. The use of a PZT patch to infer about the level of damage in the substrate requires interpreting the coupled electro-mechanical (EM) response of the PZT patch attached to the substrate.

2024年1月6日 · Lead zirconate titanate (PZT) patches gained popularity in structural health monitoring (SHM) for its sensing and cost effective. However, a robust installation of PZT...

2017年1月1日 · PZT electromechanical impedance can indicate defects on PZT main structure in early stage. Condition of the main structure can be derived from changes on PZT EMI spectrum. Electromechanical impedance provides non-invasive measurement method, while response of the main structure is not modified by the sensor [1].

2024年12月15日 · For a host plate (gray), the metasurface is constructed by PZT patches (blue), which arranged on the upper surface of host plate along 2-axis, to manipulate the propagation of flexural wave along 1-axis.

2021年2月25日 · Piezoelectric (PZT) shunt damping is an effective method to dissipate energy from a vibrating structure; however, most of the applications focus on targeting specific...

2018年7月12日 · 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.

Details of PZT patches and specimens. The advent of smart materials such as the piezo-impedance transducer (lead zirconate titanate, PZT) and optical fiber (FBG) has ushered in a new era in...

2022年6月16日 · The stress-strain response of the PZT patch embedded in the confined granular fill has been obtained in terms of charge density and voltage using a systematic numerical approach. The position of the PZT patch and its geometric properties influences the magnitude of deformation as described in the following sections. 2.2. Stress-Strain Behaviour
