Piezoelectric Cantilever

Harvesting the electrical energy from their working environment has become a feasible choice of realizing self-powered systems or providing supplementary power sources to the battery. In this paper, a pre-loaded piezoelectric cantilever bimorph (PCB) energy harvester is adopted as the research object, for which a single degree-of-freedom analytical model and finite element modeling have been carried out to study its dynamic responses. The laboratory experiments have also been performed to validate the analytical and the finite element modeling. It shows that finite element modeling has a better agreement with the experimental results than the analytical model, while the latter has a rough accuracy and can be used to obtain quick estimations of the dynamic response of the PCB energy harvester in certain cases.

The power output characteristics of an electromagnetic energy harvester which uses magnetic levitation to produce the nonlinear vibration were investigated in this paper. A finite element model was developed in the electromagnetic finite element software MAXWELL®. The results show that the power output of the harvester was strongly influenced by its external loads and structural parameters. The experimental results show that the peak power output of the electromagnetic harvester is 8.2 mW at the resonance of 8.5 Hz under the vibration acceleration of 5m/s2. That obtained from the finite element analysis is 8.5 mW at 8.4Hz. The experimental results effectively verify the validity of the finite element modeling.
