Parameter optimization for enhancing TENG by UV nanosecond laser direct writing and coupling

Abstract

TENG (triboelectric nanogenerator) has shown unique application prospect as a powerful way of harvesting renewable energy in micro-scale self-powered systems. The contact-separation (CS) arched TENG is so convenient that made a great progress in the past years. Laser ablated micro-nano structure on the surface of TENG triboelectric layers possesses a critical impact on its performance. However, arbitrary laser parameters do not provide a direct enhancement of the TENG output, but rather a different degree of degradation. The UV-nanosecond laser (Ultraviolet nanosecond laser) engraving parameters were optimised during the enhancement of the arched TENG using UV-nanosecond laser etching. Evaluation and analysis of the engraved friction layer coupling, electrode substrate arrangement and optimization curves was carried out, which provides an important reference for UV nanosecond laser etching TENG contribute to large-scale application of renewable energy.
