Abstract

A new membrane‐based triboelectric sensor (M‐TES) is presented as a self‐powered pressure change sensor. It generates a voltage induced by surface triboelectric charges in response to an air pressure change. Extremely high detection resolutions of 0.34 Pa and 0.16 Pa are achieved when the air pressure increases and decreases in a small region away from the ambient standard atmosphere pressure, respectively, indicating an excellent sensitivity. By integrating the M‐TES with a signal processing unit, we demonstrate practical applications of the device in sensing footsteps, respirations, and heartbeat, which suggests widespread use of the M‐TES in fields of security surveillance, chemical engineering, geography research, environment monitoring, and personal healthcare.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Triboelectric pressure sensors can generate output signals under pressure due to contact electrification and can function without an external power source.

    “Triboelectric pressure sensors can generate output signals under pressure due to the contact electrification.[163,164] They can function without using an external power source.”

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.
