A novel triboelectric nanogenerator based on electrospun polyvinylidene fluoride nanofibers for effective acoustic energy harvesting and self-powered multifunctional sensing
Abstract
Abstract Acoustic energy is mostly wasted without a proper energy harvesting approach. In this work, an integrated triboelectric nanogenerator (TENG) with a polymer tube is constructed to harvest acoustic energy from the environment, which can work stably in the frequency ranging from 20 Hz to 1000 Hz. The TENG is based on electrospun polyvinylidene fluoride (PVDF) nanofibers and two conductive fabrics. The unique structure design facilitates acoustic energy capturing and the enhancement of sound pressure. The TENG can deliver an open-circuit voltage and short-circuit current of 400 V and 175 µA, respectively, with instantaneous maximum output power density of 7 W/m2 under a sound frequency of 170 Hz and sound pressure of 115 dB. The TENG can be used for audio frequency analysis and noise detection. Furthermore, self-powered active sensors are demonstrated for detecting sound source direction and motion velocity of an object making sounds. This work not only provides a simple, cost-effective approach for fabricating high performance TENG to recycle ambient noise energy into available electricity, but also enables self-powered sensing applications, with potential applications in military surveillance, artificial intelligence, Internet of Things, and jet engine noise reduction.

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.
