Abstract

Implementation of wearable sweat sensors for continuous measurement of fluid based biochemical markers is an attractive alternative to common, yet intrusive and invasive, practices such as urine or blood analysis.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Most wearable sweat sensors are unable to draw low volumes of resting sweat rapidly into the device, limiting real-time assessment.

    “They are unable to draw low volumes of resting sweat rapidly into the device, limiting real-time assessment.”
  • Most wearable sweat sensors have focused on exercise, thermal, or chemically stimulated sweat produced at rates of 10's or 100's of nL min−1 cm−2 or higher.

    “For this reason, most wearable sweat sensors have focused on exercise, thermal, or chemically stimulated sweat produced at rates of 10’s or 100’s of nL min−1 cm−2 or higher10–23.”
  • Local heat generation due to on-body attachment of the patch could potentially elevate sweating rates, but negligible local heating is observed due to the small patch size and at or near rest conditions.

    “Local heat generation due to on-body attachment of the patch must also be considered as it could potentially elevate sweating rates18, but negligible local heating is observed as demonstrated in Supplementary Fig. 19 due to the small patch size and at or near rest conditions.”

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.
