Abstract
Photostrictive type of opto-thermo-electro-mechanical materials, called PbLaZrTi (PLZT), are a recently emerged family of smart materials, that are able to generate strains under illumination of near violet light and attract much attention in a variety of wireless and remote control applicati-ons, including the areas of material science and engineering, micro-electro-mechanical system (MEMS) and Optical MEMS, and smart structures. This research presents an analytical and finite element investigation into ultraviolet photo-induced multi-physics responses of 0-3 polarized PLZT photocantilever and a comparison of the measured bending displacement. The finite element formulation of the...
