Deformable, transparent, high‐performance, room‐temperature oxygen sensors based on ion‐conductive, environment‐tolerant, and green organohydrogels
Open accessAbstract
We present green organohydrogel‐based stretchable (up to 700% strain), transparent, and room‐temperature O 2 sensors with impressive performance, including drying and freezing tolerances, high sensitivity, broad detection range (100 ppm‐100%), long‐term stability, low theoretical detection limit (0.585 ppm), linearity, and the capability to real‐time monitor human respiration by directly attaching on human skin. A facile solvent replacement approach is employed to partially exchange water with natural and edible xylitol/sorbitol molecules, generating stable, green and tough organohydrogels. Compared with the pristine hydrogel counterpart, the organohydrogel‐based O 2 sensors feature higher stability, prolonged life time (140 days) and the ability to work over a wide range of temperatures (−38 to 65°C). The O 2 sensing mechanism is elucidated by investigating the redox reactions occurred at the electrode‐hydrogel interface. This work develops a facile strategy to fabricate stretchable, transparent, and high‐performance O 2 sensor using stable and green organohydrogels as novel transducing materials for practical wearable applications. image

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.
