Research the dependence of output voltage and charge on the width of Piezoelectric vibrating device
In order to make use of waste vibration energy from running car,Research on the piezoelectric vibrating device has caught more attention. The cantilever support piezoelectric vibrating device that can output more power attracts more attention to it. It has been introduced that the effect of the length and thickness for the output voltage and charge,and however the effect of the width for the output voltage and charge is rarely researched,especially when there is an identical force at free boundary. In the paper,the curved theory of vibration and piezoelectric relevance knowledge is used to analyze the piezoelectric vibrator. The analyses have shown that the voltage and charge reduce with the width of piezoelectric vibrating device. Experiments verify the analysis.
