Abstract
The accelerating arrival of the Internet of Things (IoT) era creates a rapidly growing demand for paper‐based electronics due to their low cost, light weight, flexibility, and environmental friendliness. However, manufacturing high quality circuits with ultralow sheet resistance on cellulose paper remains a challenge. Here, a method is proposed to easily fabricate hybrid copper–fiber highly conductive features on low‐cost cellulose paper with strong adhesion and enhanced bending durability. A functional coating for fast surface modification of cellulose paper via an in situ cross‐linking mechanism between pyridine and epoxy groups is developed to enhance copper–fiber adhesion and protect paper in alkaline electroless deposition bath. Thanks to the unique porous structure of cellulose paper, the electroless copper deposition occurs in a 3D manner in the inkjet‐printed area, and forms a flexible copper–fiber hybrid structure ≈90 µm thick with sheet resistances as low as 0.00544 Ω sq −1 . To demonstrate its potential applications in the IoT industry, a functional battery‐free circuit and a high‐performance planar antenna for radio frequency identification are fabricated and tested using the proposed method.

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
