We report a simple route to next-generation self-powered devices that can harvest ambient renewable energy. This work presents a new approach to fabricate a washable, breathable and wearable triboelectric nanogenerator (TENG) capable of effectively harvesting triboelectric energy through an enhanced frictional surface-area made of gold nanodot-patterns produced by a metal deposition and etching process on polyurethane surface. We have developed self-driving devices integrated with clothes that can harvest mechanical energy from friction energy through human body motion. To improve the power output performance, a waterproof fabric with a quantified friction charge against fluttering membrane (FM) and airflow rate was implemented as airflow-driven FM-TENG. Our strategy is to manufacture high-performance and cost-effective energy harvesting systems based on existing waterproof and breathable fabrics (i.e., Gore-Tex) to use sustainable and renewable energy sources. |
