Ying et al. designed AIskin by combining physically crosslinked agarose and covalently crosslinked PAM and adding Eg to form a bilayer DN hydrogel with opposite charges.
“Inspired by human skin, Ying et al. [284] designed a new hydrogel ionic electronic device to develop artificial ionic skin (AIskin) with unprecedented properties. They combined physically crosslinked agarose and covalently crosslinked PAM and added Eg to form a bilayer DN hydrogel with opposite charges.”

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.
