A High‐Durability Triboelectric Nanogenerator for Broad‐Spectrum Wind Energy Harvesting

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents an easy‐starting and high‐durability triboelectric nanogenerator (ESHD‐TENG) for efficient broad‐spectrum wind energy harvesting. By integrating a fan blade design and a mode‐switching mechanism, the device achieves a low cut‐in wind speed of 0.9 m −1s and significantly enhanced durability, addressing key challenges in current TENG ...
