Triboelectric Nanogenerator with Microstructure Fabricated by 3D Lithography at Contact Interface

Abstract

We propose a triboelectric nanogenerator with pyramidal microstructure array fabricated by 3D lithography at contact interface. Since the actual contact area of the periodic pyramidal structure is relatively easy to predict, we evaluated the relationship between the size of the pyramidal microstructure at the contact interface and the power generation performance in a vertical contact-separation mode.
