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 energy-to-electricity conversion ability. However, there is little data for the acoustic-to-electric of electrospun Here we show that nanofibre webs a strong Using poly(vinylidene fluoride) as model and sensor device transfers sound directly layer, devices can detect low-frequency with sensitivity high 266 mV Pa −1 . They precisely distinguish waves in low middle frequency region. These features make them especially suitable noise detection. Our more than five times higher commercial film device. Electrospun may be useful developing high-performance acoustic sensors.
