Mediterranean Conference on Structural Dynamics and Vibroacoustics 23-25 Apr 2013 Marrakech ( Morocco ) INTERNAL RESONANCES IN NONLINEAR NANOCANTILEVER ARRAYS UNDER ELECTROSTATIC ACTUATION

The nonlinear dynamics of nanoelectromechanical cantilever arrays is investigated using a comprehensive analytical multiphysics model that takes into account geometric and electrostatic nonlinearities. In particular, the internal resonances between the different cantilevers are analyzed using a multi-modal Galerkin discretization coupled with a perturbation technique. Such systems offer a perfect mechanical synchronization, interesting nonlinear behaviors and exchange of energy between their different components which makes them potential candidates for multi-mass sensing applications.
