Abstract

New fiber-type piezoelectric nanogenerator devices consisting of radially aligned perovskite PbTiO₃ nanotubes are designed for energy harvesting from arbitrary mechanical motion. The free-standing fiber-type nanogenerators generate constant amount of electric power by bending or wind motion regardless of direction, thus, extending the possibility of their practical applications.

Keywords: anodic oxidation; arbitrary direction; hydrothermal method; nanogenerator; piezoelectric nanotubes.
