Abstract

Vibration energy is a kind of energy form which is ubiquitous in living environment. By using the piezoelectric principle of piezoelectric ceramics, it can design a kind of vibration energy recovery device which can effectively transform the vibration energy in the environment. Because the fluctuation frequency of vibration generated by different vibration sources in the external environment is different, this paper starts from the broadband research, and uses the arrangement of the transducer array to widen the frequency band for the piezoelectric energy acquisition device. In this paper, the finite element analysis software ANSYS is used to model the piezoelectric vibrator structure of different configurations. The static analysis and modal analysis are carried out in this order. The simulation results are obtained and analyzed. And then use the harmonic response analysis, the results of the verification. Finally, based on the standard energy acquisition circuit, this paper studies the interface circuit which is suitable for the vibration model and improves the output power so that the vibration energy recovery device can work normally after the band is widened and output stable power for power supply. This study provides the basis for realizing the power supply of intelligent sensor.
