摘要
Energy conversion based on vertically aligned piezoelectric nanowire (NW) arrays is of great interest because of their unusual properties originating from large surface area/high aspect ratio and excellent piezoelectric properties. Here, perovskite-structured piezoelectric BaTiO3 NW arrays are vertically grown onto the flexible Ti substrates by a two-step hydrothermal reaction to realize an aligned 1D nanostructures-based flexible energy harvester. The BaTiO3 NW array-based flexible piezoelectric energy harvester (PEH) successfully converts a maximum open-circuit voltage of approximate to 15 V, a maximum short-circuit current of approximate to 400 nA, and an effective power of approximate to 0.27 mu W during repeated bending deformations. Under pressing with an external force of 49.57 N, the harvested output signals of the vertically aligned NW arrays-based PEH are approximate to 20 V and approximate to 60 nA. Finite element analysis with multiphysics simulation supports the hypothesis of effective potential generation by the NW arrays-based flexible PEH. These results can aid in the further development of high-output 1D nanostructures-based flexible PEHs.
