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

铅镧锆钛酸盐（PLZT）材料产生机械应变时，暴露于近紫外光作为一个综合的光伏和匡威压电效应的结果。 它们提供与压电材料相当的致动应变和其他优点，例如无线光-机械能量传输、抗电磁干扰以及透明电极设计的快速响应。 该项目旨在开拓PLZT光致动器在变形柔性结构中的应用，从而发展无线智能结构技术和光机电系统，如医疗仪器。

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.
