A novel approach converts nanoscale mechanical energy into electric energy for selfpowering nanodevices that operate independently by itself without external battery for power supply requires only a power range of only ìW to mW. In this work, piezoelectric p-type zinc-oxide nanowire (Sb doped ZnO NW) arrays were used to demonstrate this new approach of converting nanoscale mechanical energy like body motion, tiny mechanical vibration/disturbance etc., into electric energy.The nanogenerator (NG) using the piezoelectric effect of ZnO nanowires applies to tolerate the variable environment.In the design reported here, a piezoelectric ZnO nanowires on a flexible (Teflon) substrate and was fixed to electrodes at both surfaces. Periodically bending and releasing the substrate piezoelectric ZnO nanowires with therefore generates an alternating current,and has a number of advantages in terms of stability, robustness, cost, manufacturability and its ability to work in fluid and under harsh conditions. Here, the fundamental principle behind the nanogenerator was reviewed, and an approach for improving its performance was presented.We have implemented a simple,well controlled aqueous solution based doping strategy for synthesis of single crystalline Sb-ZnO nanowires rather using any other conventional,expensive vapourphase synthesis methods.The Sb doping concentration was studied with ICP-OES. The morphology and structural characterizations of the Sb-ZnO NWs were performed by SEM. The crystal structure and the functional group study were done using XRD and FTIR spectroscopy. A semi conductorconfirmatory low temperature PL study of Sb doped nanowires was also carried out.
