Abstract
Considerable interest has been devoted to converting mechanical energy into electricity using polymer nanofibres. In particular, piezoelectric nanofibres produced by electrospinning have shown remarkable mechanical-to-electricity conversion property. In this study, we show that polyvinylidene fluoride (PVDF) nanofibre nonwoven webs produced by an electrospinning technique have strong acoustoelectric conversion ability. Nanofibre characteristics affect electrical outputs. The nanofibre sensor devices are able to detect low-frequency sound, which has potential use in detecting sound.
