A piezoelectric energy harvester based on a piezoelectric beam with a ferroelectric inversion layer
2017 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA)(2017)
摘要
Flexural vibration of piezoelectric beam with a ferroelectric inversion layer is analyzed. The structure analyzed represents a kind of piezoelectric generator for converting mechanical energy from Flexural vibrations to electrical energy. Analytical expressions and numerical results for the output voltage, current, power, efficiency and power density are given.
