Abstract: The compression mode and shear mode for energy harvesting experimental platform was estabished. The energy collection efficiency of PVDF/TiO₂ nano-composite film in the two mode and nonlinear piezoelectric effect were analysed. Experimental results show that the energy collection efficiency of the shear mode was higher than the compressed mode. The Piezoelectric constant and piezoelectric coupling coefficient have nonlinear changes under large stress. In this paper, the experimental data establish a relationship electromechanical coupling coefficients and parameters of composite thin film piezoelectric stress.
