Acoustic energy harvesting using flexible panel and PVDF films: A preliminary study

Abstract

Acoustic energy harvesting from ambient noise utilizing flexural vibration of a flexible panel is investigated. A flexural vibration from the panel is use to extract more energy from the ambient noise where piezoelectric materials of PVDF films are attached around the plate edges. This preliminary study found that the energy harvesting can be obtained with a maximum output power of 120 pW at sound pressure level of 97.3 dBA. © (2014) Trans Tech Publications, Switzerland.
