Resumen en inglés | We study the performance of an electromechanical oscillator as an energy harvester driven by finite-bandwidth random vibrations under the influence of both a stiffness-type nonlinearity and a nonlinear damping that has recently been found to be relevant in the dynamics of submicrometer mechanical resonators. The device was numerically simulated and its performance assessed by means of the net electrical power and the efficiency of the conversion of the supplied power by the noise into electrical power for exponentially correlated noise. We tune the parameters to achieve a good performance of the device for non-negligible amplitudes of the nonlinearity of the oscillator and the damping |
