Piezoelectric Current Generator Based on Bismuth Ferrite Nanoparticles

Abstract

Bismuth ferrite nanoparticleswith an average particle diameter of 45 nmand spatial symmetry R3c were obtained by combustion of organic nitrate precursors. BiFeO3-silicone nanocomposites with various concentrations of nanoparticles were obtained by mixing with a solution of M10 silicone. Models of piezoelectric generators were made by applying nanocomposites on a glass substrate and using aluminum foil as contacts. The thickness of the layers was about 230 um. There was a proportional relationship between the different concentrations of nanoparticles and the detected potential. The output voltages were 0.028, 0.055, and 0.17 V with mass loads of 10, 30, and 50 mass%, respectively.Bismuth ferrite nanoparticleswith an average particle diameter of 45 nmand spatial symmetry R3c were obtained by combustion of organic nitrate precursors.
