Design and Analysis of a Steady-Voltage Piezoelectric Transducer

As micro-electromechanical systems (MEMS) and smart technologies have been more matured, applications for wider fields are more available.
Piezoelectric materials have the property of electromechanical energy conversion, which can convert vibration energy into electrical energy.
In this paper, a general concept of the piezoelectric energy conversion is first given. Then, a simple modeling design and analysis for a special transverse mode of the piezoelectric generator called mode 31 is presented.
With regard to analytical method, the piezoelectric equivalent circuit model is able to illustrate the important parameters that influence the process how the piezoelectric element generates electrical energy.
We may adjust unimorph voltage by controlling the deflection of cantilever beam. And the output power is taken as the indicated parameters for the generator. The energy conversion efficiency of the generator depends on the operation frequency.
By using this way, the piezoelectric power generator may be widely applied to environment with both low-frequency and high-frequency vibration range.
