The modelling of a piezoelectric vibration powered generator for microsystems
The modelling of a piezoelectric vibration powered generator for microsystems
As MEMS and Smart Material technologies advance, embedded and remote applications are becoming more widespread. Powering these systems can be a significant engineering problem, as traditional solutions such as batteries are not always appropriate. A method is described for modelling the power than can be produced from piezoelectric inertial generators. The method uses a combination of FEA and a complex stiffness model of a resistively shunted piezoelectric element. The model is verified with experimental results. Although the prototype produces only 3µW, the model reveals that orders of magnitude increase in power output are possible.

Abstract
As MEMS and Smart Material technologies advance, embedded and remote applications are becoming more widespread. Powering these systems can be a significant engineering problem, as traditional solutions such as batteries are not always appropriate. A method is described for modelling the power than can be produced from piezoelectric inertial generators. The method uses a combination of FEA and a complex stiffness model of a resistively shunted piezoelectric element. The model is verified with experimental results. Although the prototype produces only 3µW, the model reveals that orders of magnitude increase in power output are possible.
