Abstract

This article delves into the development and evaluation of triboelectric nanogenerators (TENGs) using 3D-printed polylactic acid (PLA) and PLA-carbon fiber (PLA-CF) sheets as triboelectric layers. The study emphasizes the use of biodegradable polymers and solvent-free fabrication techniques to create sustainable energy-harvesting devices. Key topics include the physicochemical properties of PLA and PLA-CF composites, the fabrication process of TENG devices, and their electrical performance. The research demonstrates that incorporating carbon fibers into PLA enhances mechanical strength, surface roughness, and triboelectric output. The fabricated TENG devices show promising results in powering LEDs and functioning as self-powered touch sensors, highlighting their potential in energy harvesting and smart sensing applications. The article also discusses the environmental stability and long-term performance of the devices, providing a comprehensive overview of the advantages and challenges associated with PLA-based TENGs.
