Abstract

In this article, a comprehensive model of a micro-switch subjected to piezoelectric excitation, which accounts for the nonlinearities due to inertia and curvature, is presented. Dynamic equations of this model is derived by the Lagrange method and solved by the Galerkin method using five modes. Micro-switch movable part is assumed as an elastic Euler-Bernoulli beam with clamped-free end conditions. Whereas the major drawback of electrostatically actuated micro-switches is the high driving voltage, using the piezoelectric actuator in these systems can provide less driving voltage. The effect of variation in geometry of piezoelectric layer such as length and thickness as well as piezoelectric voltage on mechanical characterizations is discussed. The aim of this work is to design and control of a micro-switch with the change in length and thickness of the piezoelectric actuator.
