Study of the Tip Deflection in Static State of a Piezoelectric Polymer based Bimorph Actuator with Varying Thickness and Length Ratios

چکیده
Piezoelectric cantilevers have been in great demand in sensor and actuator applications. The tip displacement of the cantilever is the most important and sensitive parameter in the actuation mode. Hence, in this study a bimorph cantilever beam has been chosen as the element of study consisting of two active piezoelectric layers of PVDF bonded together. An attempt has been made to establish the expression of tip deflection of a bimorph cantilever beam of different piezoelectric. This bimorph cantilever is designed and the results are simulated using COMSOL Multiphysics software. The analytical results and simulated data are found to be in close agreement with each other, hence validating the expression of tip deflection of a bimorph cantilever beam. KeywordsActuator, Cantilever, Polyvinylidene fluoride (PVDF).
