  • Patent number: 10673355
    Abstract: A nano-generator includes a counterpart layer, and an electricity producing unit producing frictional electricity according to frictional contact with the counterpart layer, wherein the electricity producing unit includes a contact layer provided on one surface of the electricity producing unit and coming into contact with the counterpart layer, a support layer provided on the other surface of the electricity producing unit, and a plurality of first electrode layers stacked between the contact layer and the support layer and disposed to be spaced apart from each other. Since the contact electrification nano-generator harvests energy (current), regardless of direction (mode) of a mechanical movement, an energy output of the contact electrification nano-generator may be increased.
    Type: Grant
