Summary: By studying the vibrating process of flutter-driven triboelectric nanogenerator, researchers found that the inhomogeneous charge distribution and inconsistent separation distance on the vibrating films contribute to the low electrical output. To overcome this issue, the large area vibrating films were segmented and integrated to create a high output contact-separated triboelectric nanogenerator. The optimized design achieved a transferred charge density per time of 22.25 mC s-1 m-2, which is 2.8 times the previous record, and could light up 2792 LEDs under gentle wind.

Summary: Currently, the focus is on wind energy harvesting, but existing electromagnetic wind generators struggle to capture various types of wind. Wind-driven triboelectric nanogenerators (TENGs) have been studied as an alternative to harness wind energy at different speeds, but their power output is typically low. In this study, a charge-polarization-based flutter-driven TENG (CPF-TENG) with an ambient air ionizing channel (AAIC) is introduced to overcome this limitation. The CPF-TENG with AAIC generates peak voltage and current outputs of 2000 V and 4 A, respectively, enabling it to be stacked in series for complete wind energy harvesting.

Summary: This study achieves the comprehensive integration and synergetic utilization of triboelectrification, electrostatic induction, and electrostatic discharge in a single device, realizing a dual-functional TENG (DF-TENG) to produce an AC/DC convertible output. Unlike conventional TENGs, the coupling of triboelectrification and electrostatic discharge enables charge circulation between the dielectric tribo-layers, while electrostatic induction realizes charge transfer in the external circuit. This research not only provides a paradigm shift to achieve AC/DC convertible output, but it also exhibits high potential for extending the TENG design philosophy.
