Grating‐Structured Freestanding Triboelectric‐Layer Nanogenerator for Harvesting Mechanical Energy at 85% Total Conversion Efficiency
Abstract
A newly-designed triboelectric nanogenerator is demonstrated which is composed of a grating-segmented freestanding triboelectric layer and two groups of interdigitated electrodes with the same periodicity. The sliding motion of the grating units across the electrode fingers can be converted into multiple alternating currents through the external load due to the contact electrification and electrostatic induction. Working in non-contact mode, the device shows excellent stability and the total conversion efficiency can reach up to 85% at low operation frequency.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
Freestanding mode is unaffected by electrostatic shielding and minimizes friction between triboelectric layers, resulting in high device mechanical durability and energy conversion efficiency.
“In contrast to the single-electrode mode, the freestanding mode is unaffected by the electrostatic shielding effect and minimizes friction between the triboelectric layers, resulting in high device mechanical durability and energy conversion efficiency.[92,138]”

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.
