Morphing flexible structures with lead lanthanum zirconium titanate (PLZT) based optical actuators

镧钛酸铅(PLZT)材料在近紫外光照射下，由于光伏和逆压电效应的综合作用，产生机械应变。它们提供了与压电材料同等的致动应变和其他优势，如无线光到机械能量传递、不受电磁干扰的免疫以及透明电极设计的快速响应。该项目旨在开创PLZT光学驱动器在变形柔性结构中的应用，从而促进无线智能结构技术和医疗器械等光电系统的发展。

Lead lanthanum zirconate titanate (PLZT) materials yield mechanical strains when exposed to near ultraviolet light as a result of combined photovoltaic and converse piezoelectric effects. They offer actuation strain on par with piezoelectric materials and other advantages, such as wireless light-to-mechanical energy transfer, immunity from electrical and magnetic disturbances and fast response with the transparent electrode design. This project aims to pioneer the application of PLZT optical actuators in morphing flexible structures leading to development of wireless smart structures technology and opt-electromechanical systems such as medical instruments.
