Abstract: Using the two-parameter model of the thin film-substrate system, the bending of the single-layer barium titanate (BaTiO3) nano-film system under axial stress was studied. The polarization intensity, polarization charge and piezoelectric potential distribution of BaTiO3 nano-film were analyzed and discussed. According to the mechanical balance method, the bending piezoelectric potential, the bending curvature radius and the strain of the BaTiO3 thin film were solved. The results showed that, the theoretical model and results of this paper are in good agreement with the experimental data and finite element simulation reported by Park et al, providing a simple theoretical model and basis for the mechanism of piezoelectric nanofilm generators.
