Ferroelectric behavior in strained SrTiO3 nano porous is investigated using phase-field simulations. We find, in the paraelectric nano-porous, the polarization vortex emerges around each pore due to strain concentration and forms a periodically arrayed ferroelectric nano region. The ferroelectric region expands and connects each other with increasing strain, and finally forms a ferroelectric network, which can be regarded as a nanostructure. Our finding provides a new strategy to tailor ferroelectric nano structure through mechanical load.
