Recently, the piezoelectric nanogenerators(NGs) based on flexible substrates have attracted considerable interest. In this study, ZnO nanorods were employed to fabricate the piezoelectric NGs. We examined the effect of seed-layer on the structural properties of ZnO nanorods grown on flexible ITO substrate by hydrothermal method. The effect of reaction time and temperature on the growth of ZnO nanorods are also investigated. The seed layer and ZnO nanorods were in detail characterized by field-emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM). We have studied the performance enhancement of piezoelectric NGs with optimal ZnO nanorod structure on flexible ITO substrate. The maximum output current, which was enough for driving of microelectronics could be measured. Our NGs are expected to provide effective and useful approach for the smart sensor devices. |
