In this paper, we fabricated transparent flexible nanogenerators (NGs) by employing flexible polydimethylsiloxane (PDMS) substrate for the growth of ZnO nanowires. The fully packaged NG showed good transparency with a transmittance of 50-60% in the visible range. The output voltage and current was 8 V and 0.6 mu A, respectively, corresponding to an output power density of similar to 5.3 mW/cm(3). The NG also showed excellent robustness and could stably scavenge energy from the motion of a vehicle. Based on this characteristic, we demonstrated its application as a self-powered sensor for monitoring vehicle speed and detecting vehicle weight. (C) 2012 Elsevier Ltd. All rights reserved.
