Numerical modelling of micro energy harvesting systems based on piezoelectric composites polarized with interdigitated electrodes
(IOP Publishing, 2020-07)
This paper focuses on the numerical modelling of micro-energy harvesting systems(MEHSs) based on piezoelectric composites polarised with interdigitated electrodes (PCPIE). The system response and the harvested energy are ...
Vibration attenuation and energy harvesting in metastructures with nonlinear absorbers conserving mass and strain energy
(2022-01-01)
In this work, we explore the performance of vibration attenuation and energy harvesting of a metastructure with vibration absorbers with nonlinear stiffness under harmonic excitation. We devise the metastructure with two ...
On the performance of a dual-mode non-linear vibration energy harvesting device
(Sage Publications Ltd, 2012-09-01)
The research trend for harvesting energy from the ambient vibration sources has moved from using a linear resonant generator to a non-linear generator in order to improve on the performance of a linear generator; for ...

Energy harvesting from the vibrations of a passing train: Effect of speed variability
(2016-10-03)
This paper builds on a previous study which investigated the amount of energy that could be harvested from the vibration induced by a passing train using a trackside energy harvester. In that study, the optimum parameters ...
A novel up-converting mechanism based on double impact for non-linear piezoelectric energy harvesting
(IOP Publishing, 2020-11-01)
In this paper we show the importance of double impact in an up-converting mechanism by usinga resonant low-frequency driving beam across a high-frequency piezoelectric beam, to enhancethe electrical output power in a ...
