Abstract
While cellulose-based stretchable hydrogels have been extensively explored in recent years, all-cellulose hydrogels continue to face the limitation of low stretchability (less than 250 %). Herein, for the first time, we fabricate an all-cellulose hydrogel with ultrahigh stretchability that can exceed 40000 % strain. By ring opening reaction on cellulose anhydroglucose unit rings, secondary hydroxyls are converted to primary hydroxyls, enabling enhanced chain flexibility, and facilitating the formation of abundant hydrogen bonds. As a result, the obtained hydrogel displays remarkable characteristics, including record-high stretchability (44200 %), rapid self-healing property (within seconds), and the unique ability to form cellulose fiber. With simple drawing, a smooth and flexible cellulose fiber can be obtained, demonstrating good processability and a high tensile strength of 226 MPa. Furthermore, the all-cellulose hydrogel can function as a human motion sensor and electrocardiogram electrode for monitoring physiological signals. This simple yet highly effective method will not only propel the advancement of ultrastretchable all-cellulose hydrogels but also create new possibilities for wearable device applications.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
