TL;DR: In this article, the authors investigated the potential of using a piezoelectric energy harvester to concurrently harness energy from base excitations and vortex-induced vibrations, and the results showed that there is a significant improvement in the level of the harvested power which can attain 150% compared to using two separate harvesters.

TL;DR: In this paper, the concept of harvesting energy from vortex-induced vibrations (VIVs) by introducing nonlinear attractive magnetic forces is proposed and investigated for the first time, where the authors designed broadband synchronization regions for efficient piezoelectric energy harvesting from VIVs of circular cylinders.

TL;DR: In this article, a nonlinear distributed-parameter model for harvesting energy from vortex-induced vibrations of a piezoelectric cantilever beam with a circular cylinder attached to its end is presented.

TL;DR: In this paper, the characteristics and performances of four distinct vortex-induced vibrations (VIVs) piezoelectric energy harvesters are experimentally investigated and compared, and the results lead to the conclusion that the bluff body should be aligned with the beam for low wind speeds.

TL;DR: In this article, the authors developed a nonlinear theoretical model for cantilevered microbeams and explored the nonlinear dynamics based on the modified couple stress theory, taking into account of one single material length scale parameter.
