This paper introduces the composition and working principle of the triboelectric nanogenerator.The ellipsoidal triboelectric nanogenerator is designed to effectively collect wave energy in multiple directions and realize the external output of electric charge.The ellipsoidal shell is more beneficial to the dense row arrangement in the sea.The internal layered design with different frictional power generation principles widens the frequency range of collected waves.With multi-directional collection function,it is more adaptable to the changing direction of waves.Through motion simulation,the motion response of the generator under different working conditions is obtained,and the wave height range is determined.The research in this paper lays the foundation for the research,development and application of multi-directional wave energy triboelectric nanogenerators.
