Development of 3D knitted fabrics for triboelectric energy generation

Abstract

The demand for sustainable energy solutions has been driving the exploration of alternative energy generation technologies. Triboelectric nanogenerators (TENGs) are one such promising solution, capable of converting mechanical energy into electrical energy by exploiting[1] the triboelectric effect. TENGs offer a clean, renewable source of energy by harnessing movements, vibrations, and friction from human activity. With the increasing popularity of wearable technology, integrating energy-harvesting fabrics into clothing presents a significant opportunity to create selfpowered systems. [2] This study focuses on developing 3D knitted fabrics specifically designed for triboelectric energy generation. Traditional fabrics are limited in their surface area and mechanical properties, leading to suboptimal energy harvesting efficiency. By utilizing advanced knitting techniques to create three-dimensional structures, the potential for maximizing the triboelectric effect is enhanced. The primary goal of this project is to develop durable, flexible, and efficient 3D knitted fabrics that can power low-energy electronics, such as sensors, through human movement.[3]
