Abstract

image

Flexible and integratable nanogenerators made from sponge-like mesoporous piezoelectric polyvinylidene fluoride (PVDF) thin films can be directly attached to an electronic device, and effectively convert mechanical energy from ambient surface oscillations to electricity. These devices provide a promising solution for developing practical self-powered electronic devices.
