Large array electrospun PVDF nanogenerators on a flexible substrate

摘要

This paper presents PVDF (Polyvinylidene fluoride) based electrospun nanofibers as nanogenerators in series and/or in parallel to amplify harvested energy due to mechanical strain on a flexible substrate. A chemically resistive flexible polymer substrate has been used with patterned comb-shape gold electrodes by means of a conventional lithography process. A total of 500 parallel nanofibers have been fabricated and connected to amplify current outputs under repeated mechanical straining tests. Peak current of 35nA has been collected with a 0.2mV of peak voltage.
