An Array of Flag-Type Triboelectric Nanogenerators for Harvesting Wind Energy
Open accessAbstract
Harvesting wind energy from the ambient environment is a feasible method for powering wireless sensors and wireless transmission equipment. Triboelectric nanogenerators (TENGs) have proven to be a stable and promising technology for harvesting ambient wind energy. This study explores a new method for the performance enhancement and practical application of TENGs. An array of flag-type triboelectric nanogenerators (F-TENGs) for harvesting wind energy is proposed. An F-TENG consists of one piece of polytetrafluoroethylene (PTFE) membrane, which has two carbon-coated polyethylene terephthalate (PET) membranes on either side with their edges sealed. The PTFE was pre-ground to increase the initial charge on the surface and to enhance the effective contact area by improving the surface roughness, thus achieving a significant improvement in the output performance. The vertical and horizontal arrays of F-TENGs significantly improved the power output performance. The optimal power output performance was achieved when the vertical parallel distance was approximately 4D/15 (see the main text for the meaning of D), and the horizontal parallel distance was approximately 2D. We found that the peak output voltage and current of a single flag-type TENG of constant size were increased by 255% and 344%, respectively, reaching values of 64 V and 8 μA, respectively.

Single-electrode mode offers the simplest TENG structure design, but its performance can be hampered by electrostatic shielding.
“While the single-electrode mode offers the simplest TENG structure design, its performance can be hampered by electrostatic shielding.[136,137]”
From Advances in Blue Energy Fuels: Harvesting Energy from Ocean for Self‐Powered Electrolysis (2025) · cites this paper as [137]
Sections 2.1–2.2 describe a contact-mode freestanding F-TENG with two electrodes, not the relative simplicity of single-electrode mode. Searches for “single-electrode” and “shielding” found no passage addressing whether electrostatic shielding hampers that mode’s performance. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
