TL;DR: In this paper, the effect of piezoelectric actuation on the resonance frequencies of a capacitive clamped-clamped microbeam is studied. And the authors show that for small amplitudes of harmonic excitation and high enough quality factor, the frequency response curves obtained by the shooting method are validated with those of the multiple time scales technique.

TL;DR: In this article, a bimorph piezoelectric micro cantilever exposed to harmonic base excitation is investigated and the output power in terms of the load resistance of the output circuit, exhibits Lorenzian behavior revealing the multi factorial dependency of the power on the governing parameters.

TL;DR: In this paper, the dynamics of an energy harvesting device based on magnetostrictive material (MSM), Metglas, subjected to low frequency base excitation is studied and the steady state output power in terms of the excitation frequency is determined and the corresponding steady state current and voltage are presented.

TL;DR: In this paper, the authors investigated the nonlinear chaotic dynamics of a clamped-clamped micro-beam exposed to simultaneous electrostatic and piezoelectric actuation, and the results showed that the response of the system can be highly nonlinear and in some regions chaotic.

TL;DR: In this paper, the stability analysis of transverse motions of a cantilever microbeam sandwiched by two piezoelectric layers located on the lower and upper surfaces of the microbeam is investigated.
