Electrical power generator from randomly oriented electrospun poly(vinylidene fluoride) nanofibre membranes

Randomly oriented electrospun poly(vinylidene fluoride) nanofibre membranes were directly used as active layers to make mechanical-to-electrical energy conversion devices. Without any extra poling treatment, the device can generate voltage outputs as high as several volts upon receiving a mechanical impact. The device also showed long-term working stability and the ability to drive electronic devices.
