Enhanced low-frequency vibration energy harvesting with inertial ...

Although several effective approaches have been proposed to maximise harvested power, a fundamental limitation of energy harvesters exploiting linear vibration is that the harvested power reduce significantly when the resonance frequency of a harvester is far from the driving frequency (Ali et al., 2010).The frequency content of the majority of ambient …

A viscoelastic metamaterial beam for integrated vibration

This paper designs an integrated viscoelastic metamaterial for energy harvesting and vibration isolation. The viscoelastic metamaterial is achieved by a viscoelastic beam periodically arrayed with spatial ball-pendulum nonlinear energy harvesters. The nonlinear resonator with an energy harvesting function is achieved by placing a free-rolling ...

Energy harvesting from quasi-periodic vibrations

Quasi-periodic (QP) vibration-based energy harvesting is studied in this paper. The energy harvesting system consists in a delayed van der Pol oscillator with time-varying delay amplitude coupled to an electromagnetic energy harvesting device in which the vibration source is due to self-excitations. We consider the case of delay parametric resonance for which the …
