摘要：

A smart piezoelectric cantilever beam (SPCB) is often used to make self-powered vibration sensors. The structure of an SPCB is investigated in this study. The equation of the output voltage of an SPCB under vibration is established and the output voltage of the SPCB is analyzed. It is found that the output voltage of the SPCB has a positive proportional relationship with the displacement of its right end. The output voltage is also related to the piezoelectric fiber material (PFM), the electrode layer, and the thickness, width, and length of the SPCB.
