, Article Microelectronic Engineering ; Vol. 119 , May , 2014 , pp. 37-43 ; ISSN: 01679317 ; Zabihollah, A ; Vesaghi, M ; Kolbadinejad, M ; Sharif University of Technology
Abstract
This research presents an application of transparent lanthanum-modified lead zirconate titanate (PLZT) materials in micro light source tracking device, which is designed to function as a result of irradiation, having neither lead wires nor electric circuits. The focus of the paper is on the analytical and finite element investigation into ultraviolet photo-induced multi-physics responses of PLZT photocantilever and a comparison of the measured bending displacement to check the feasibility of these materials in design of micro light source tracking device. The finite element formulation of the transverse deflection for multi-physics analysis of PLZT ceramics by including the photovoltaic and...
