Abstract
Abstract Nowadays, aiming to fight against environmental pollution and energy crisis, a great amount of effort has been performed on self‐powered devices. Herein, assembling a wind‐driven triboelectric nanogenerator (TENG) and a pressure sensitive elastic polyimide (PI)/reduced graphene oxide (rGO) foam together, a self‐powered pressure sensor system has been designed and investigated. Employing Ag nanoparticles and nylon film as electrode and vibration membrane, the TENG can generate desirable output. Meanwhile, the PI/rGO foam acts as the pressure sensitive unit. Integrating a bulk of PI/rGO foam (14 mm × 14 mm × 30 mm), the TENG could generate output voltage and current up to 130 V and 7.5 µA with an effective working area of 100 mm × 15 mm. Additionally, the as‐fabricated device presents various stress sensing scopes and sensitivities, when different heights of foams are integrated on the TENG. The self‐powered pressure sensor achieves a great combination between new clean energy resources and traditional pressure sensor.

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
