“…Researchers have proposed design and efficiency enhancement methods for harnessing energy from pre-existing base vibrations [1][2][3][4]24,25]. Others have reported to harness energy from wind by exploring aeroelastic instabilities, such as galloping, flutter, vortex-induced vibration (VIV), etc [5][6][7][8][9][10][11][12][13][14][15]. Indeed, these two types of kinetic energy sources, i.e., base vibration and wind energy, are coexisting in many environments, like ocean buoys, bridges and vehicles.…”
