Abstract

Photoslrictive material is emerging as a new actuation medium. In contrast to traditional transducers, photoslrictive material can produce actuation strains as a result of irradiation from incident light, baving neither electric lead wires nor electric circuits. In this paper, a static analytical model is derived for a Jiexural beam with surface-bonded photoslrictive optical actuators. Analysis of the proposed model is carried out by considering the induced force and bending moment produced on the beam by the patched acluator. Analylical solutions of the transverse deflection, induced by the photostric-live actuators, are derived. Those solutions are explicitly expressed in terms of the geometry and position of the actuators patched on the beam. The developed model is validated through experiment: There is a good agreement between the theory and experiment. Based on this study, a lab module has been developed for undergraduate technology and engineering courses.
