Abstract

fetched live from OpenAlex

Abstract Biomimetic flexible electronics for E‐skin have received increasing attention, due to their ability to sense various movements. However, the development of smart skin‐mimic material remains a challenge. Here, a simple and effective approach is reported to fabricate super‐tough, stretchable, and self‐healing conductive hydrogel consisting of polyvinyl alcohol (PVA), Ti 3 C 2 T x MXene nanosheets, and polypyrrole (PPy) (PMP hydrogel). The MXene nanosheets and Fe 3+ serve as multifunctional cross‐linkers and effective stress transfer centers, to facilitate a considerable high conductivity, super toughness, and ultra‐high stretchability (elongation up to 4300%) for the PMP hydrogel with. The hydrogels also exhibit rapid self‐healing and repeatable self‐adhesive capacity because of the presence of dynamic borate ester bond. The flexible capacitive strain sensor made by PMP hydrogel shows a relatively broad range of strain sensing (up to 400%), with a self‐healing feature. The sensor can precisely monitor various human physiological signals, including joint movements, facial expressions, and pulse waves. The PMP hydrogel‐based supercapacitor is demonstrated with a high capacitance retention of ≈92.83% and a coulombic efficiency of ≈100%.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
