Design of tunable low-frequency acoustic energy harvesting barrier for subway tunnel based on an optimized Helmholtz resonator and a PZT circular plate
This paper presents a tunable, low-frequency acoustic energy harvesting barrier, which contains the following four parts: the noise acquisition input module, the Helmholtz resonator optimization module, the resonant frequency tuning module, and the electricity generation module. The aim of this stud...
