A piezomagnetoelastic structure for broadband vibration energy harvesting
(AIP Publishing, 2009-06-01)
This letter introduces a piezomagnetoelastic device for substantial enhancement of piezoelectric power generation in vibration energy harvesting. Electromechanical equations describing the nonlinear system are given along ...
A piezoelectric bistable plate for nonlinear broadband energy harvesting
(AIP Publishing, 2010-09-01)
Recently, the idea of using nonlinearity to enhance the performance of vibration-based energy harvesters has been investigated. Nonlinear energy harvesting devices have been shown to be capable of operating over wider ...
Nonlinear piezoelectricity in electroelastic energy harvesters: Modeling and experimental identification
(American Institute of Physics, 2010-10-01)
We propose and experimentally validate a first-principles based model for the nonlinear piezoelectric response of an electroelastic energy harvester. The analysis herein highlights the importance of modeling inherent ...
Modeling of distributed piezoelectric actuators integrated with thin cylindrical shells
(Acoustical Society of America, 1994-09-01)
The dynamic interaction between induced strain piezoelectric (PZT) actuators and their host structures is often ignored in the modeling of intelligent structures. A more realistic investigation of intelligent material ...
