Synthesis and fabrication of zinc oxide nanostrands based piezoelectric nanogenerator

Development in the field of energy generation has always been a topic of great interest. In this work a new type of Zinc Oxide pattern (fibre-like thin strands) is grown on aluminium substrate. Uncomplicated Hydrothermal method using Zinc nitrate hexahydrate and hexamethylenetetramine is adopted for growing Zinc Oxide nanostrands. The surface morphology and composition was revealed by Scanning electron microscopy, Energy dispersive spectroscopy and X-ray diffraction. The so grown film was then employed in the fabrication of nanogenerator that can harvest energy up to 150 mV and 400 nA. This much power production is enough to be supplied to self- powered nanosystem. Moreover simplicity of this method might make synthesis to device fabrication much more of a commercial reality. Simulation results of such a nanostrand structure are also depicted in this paper that are in conformity with piezoelectric nanogenerators.
