In this paper, a flexible nanogenerator based on direct piezoelectric effect using a spin-coated poly(vinytidenefluoride-co-trifluoroethylene) (PVDF-TrFE) thin film as functional layer has been fabricated on polyimide substrate. The as-prepared nanogenerator exhibits the open-circuit voltage up to 7 V and short-circuit current of 58 nA with current density of 0.56 mu A/Cm-2. The impact of the variation of strain rate on the electrical outputs of the nanogenerator has been characterized experimentally and analyzed theoretically. An analytical model that explains well the experimental results has been established. (C) 2014 Elsevier Ltd. All rights reserved.
