New fiber‐type piezoelectric nanogenerator devices consisting of radially aligned perovskite PbTiO 3 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.
