Dynamic Analysis of Multilayers Based MEMS Resonators

The dynamic behavior of a microelectromechanical system (MEMS) parallel and electrically coupled double-layers (microbeams) based resonator is investigated. Two numerical methods were used to solve the dynamical problem: the reduced-order modeling (ROM) and the perturbation method. The ROM was derived using the so-called Galerkin expansion with considering the linear undamped...

Uncertainty Quantification of Piezoelectric Energy Harvesters from Aeroelastic Vibrations

A stochastic approach is presented to evaluate the uncertainties associated with variations in design parameters of a piezoaeroelastic energy harvester. The sensitivities of the harvested power to variations in the load resistance, the eccentricity (distance between the center of mass and the elastic axis), and the nonlinear coeffcients are also determined. Moreover, the non...
