1. A rotational triboelectric nanogenerator for a neuro-stimulator, comprising:
a disk-shaped electrode unit;
a first charging body stacked on an upper surface of the electrode unit; and
a second charging body having a charge opposite to that of the first charging body and disposed on an upper surface of the first charging body,
wherein the first charging body is provided to serve as a substrate,
wherein the second charging body includes a plurality of fan shape pieces, each of the plurality of the fan shape pieces being spaced apart from each other at a predetermined interval,
wherein the second charging body is disposed concentrically with the electrode unit and the first charging body, and is configured to be rotatable with respect to at least one or more of the electrode unit and the first charging body, and
wherein the second charging body is configured to rotate independently from the electrode unit.
