Research progress on piezoelectric acoustic transducers: Principles, materials, performance, and applications
Jishen Zhu
Abstract:Piezoelectric acoustic transducers enable the mutual conversion between mechanical energy and electrical energy. In recent years, piezoelectric transducers, as efficient and reliable sustainable energy harvesting devices, have demonstrated unique application value in various disciplines such as physics, acoustics, and engineering. This paper comprehensively reviews the current research status and future development directions of acoustic transducers. Firstly, the physical mechanism of the piezoelectric effect … Show more
