However, with the existing electromagnetic wind generators, it is difficult to harvest multifariously-wasted breezes. To harvest energy from winds at a wide range of speeds, wind-driven triboelectric nanogenerators (TENGs) are studied. However, a critical limitation of general wind-driven TENGs is that their power output is low. Therefore, an innovative strategy is necessary to generate high output power even from breeze. Herein, an approach to test a charge-polarization-based flutter-driven TENG (CPF-TENG) with ambient air ionizing channel (AAIC) is reported. Owing to AAIC, the device generates peak voltage and current outputs of 2000 V and 4 A, respectively. Moreover, because the proposed CPF-TENG can generate power from breeze, it can be stacked in series to completely harvest wind energy. The stacked CPF-TENG is demonstrated to operate 3000 light-emitting diodes (LEDs) and 12 hygrometers, separately, and produce hydrogen at a rate of 342.3 µL h−1 with the electrolysis cell.enambient-air-ionizing channels | breeze energy harvesting | charge-polarization-based flutters | stackable | triboelectric nanogeneratorsjournal article10.1002/adma.202300283369332292-s2.0-85154070767WOS:000977793000001https://api.elsevier.com/content/abstract/scopus_id/85154070767
