Abstract
A triboelectric generator includes a ferroelectric material layer and a protective layer provided over the ferroelectric material layer including first and second electrodes that are spaced apart from each other, a polarized ferroelectric material layer provided over the first electrode and configured to generate electrical energy by contact with another material, and a protective layer provided over the ferroelectric layer to prevent diffusion of charges generated on the ferroelectric layer.
