Special Issue Information

Dear Colleagues,

Vibration energy harvesters have recently attracted substantial attention given their potential application in self-powered systems. Among various vibration sources, kinetic energy at low frequency abundantly exists in ambient environment generated by human, animal, and natural activities. However, it is a big challenge to harvest energy from kinetic energy at low frequency, especially for human motion and ocean wave, because the harvested power is generally proportional to the square of frequency. Under this circumstance, many researchers have paid their efforts on this area; however, there are still some scarcities in the device’s size, structure complexity, and energy conversion efficiency, which should be further improved.

Accordingly, this Special Issue aims to showcase research papers, short communications, and review articles outlining recent progress and innovative approaches for kinetic energy harvesters at low frequency. The applications of energy harvester at low frequency, such as the self-powered sensing system, are also welcome and strongly encouraged.

We look forward to receiving your contributions!

In this paper, we consider novel bursting energy harvesting under combined external and parametrical slow excitations, and a harvester is realized by employing an externally and parametrically excited post-buckled beam. Based on the method of fast–slow dynamics analysis, multiple-frequency oscillation, with two slow commensurate excitation frequencies, is used to observe complex bursting patterns, the behaviors of the bursting response are presented, and some novel one-parameter bifurcation patterns are observed. Furthermore, the bursting harvesting performances of the single and the two slow commensurate excitation frequencies are compared, and it was found that the two slow commensurate excitation frequencies can be used to improve the harvesting voltage.
