Structural Design Approaches for Omnidirectional Wind Energy Harvesting using Triboelectric Nanogenerators

Аннотация

The development of efficient and robust wind energy harvesting systems is essential to meet the growing demand for sustainable and decentralized energy sources. This study explores structural design strategies for omnidirectional wind energy harvesting using triboelectric nanogenerators (TENGs). By leveraging the triboelectric effect and advanced material configurations, TENG-based systems offer significant potential for low-cost, lightweight, and scalable wind energy solutions. Various structural designs, including flutter-driven, rotary, and hybrid configurations, are analyzed with respect to their mechanical-to-electrical energy conversion efficiency, adaptability to multi-directional airflow, and environmental durability. The paper also discusses design optimizations that enhance charge transfer, frequency response, and energy output under fluctuating wind conditions. Experimental prototypes and simulation results demonstrate the feasibility and performance of these approaches, highlighting their applicability in powering small electronic devices, sensors, and microgrids, particularly in remote or urban environments with variable wind directions.
