Abstract

Extremely stretchable self-healing strain sensors based on conductive hydrogels are successfully fabricated. The strain sensor can achieve autonomic self-heal electrically and mechanically under ambient conditions, and can sustain extreme elastic strain (1000%) with high gauge factor of 1.51. Furthermore, the strain sensors have good response, signal stability, and repeatability under various human motion detections.

  • Encapsulation of hydrogel sensors with elastomeric materials is an effective approach to prevent the evaporation of water from hydrogels.

    “The encapsulation of hydrogel sensors with elastomeric materials is an effective approach to prevent the evaporation of water from hydrogels”

    From Functionalized Hydrogel-Based Wearable Gas and Humidity Sensors. (2023) · cites this paper as [153]

    The paper describes using elastomeric VHB tape as the sensor’s encapsulant and says appropriate encapsulation can reduce water loss (passages [6] and [2], both labeled Abstract; no page given). But it reports water evaporation during extended cycling and does not establish that elastomeric encapsulation effectively prevents it. (LLM, conf=0.87)

  • SWCNT/hydrogel was reported to be able to detect strain as large as 1000% owing to the self-healing capability of the hydrogel.

    “Very recently, SWCNT/hydrogel was reported to be able to detect strain as large as 1000% owing to the self-healing capability of the hydrogel.[117]”

    From Nanomaterial-Enabled Wearable Sensors for Healthcare (2018) · cites this paper as [117]

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.
