Sulfur-doped-ZnO-nanospire-based transparent flexible nanogenerator self-powered by environmental vibration

Abstract

An S-doped-ZnO-nanospire-based nanogenerator that converts environmental vibration into electrical energy is proposed. The nanogenerator piezoelectricity is improved by loading weight, ultraviolet (UV), and a sharp Pt/ZnO nanowire electrode. The output current and voltage of the nanogenerator in the dark and under UV light are ∼4.32 × 10⁻⁸ A and ∼0.646 V and 5.73 × 10⁻⁸ A and ∼0.689 V.
