Abstract
The present invention relates to a spherical triboelectric nanogenerator. A spherical triboelectric nanogenerator according to the present invention includes a case having an inner space in a round shape and provided with an electrode layer, and a charged body located in the inner space and movable by external force, wherein the case includes an inner charged layer formed on an inner surface of the electrode layer to be contactable with the charged body, and an outer charged layer formed to surround an outer surface of the electrode layer, and wherein electricity is generated based on at least one of friction between the outer charged layer and an external fluid and friction between the inner charged layer and the charged body, which is generated as the charged body is moved due to external force applied by the fluid.
