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.
