Abstract
Here, we report a facile fabrication of flexible piezoelectric sensors based on highly aligned poly(vinylidene fluoride) (PVDF) nanofibers and printed silver electrodes without any additional poling processes. One-dimensional (1-D) piezoelectric PVDF nanofibers are directly produced onto stamped and sprayed interdigitated electrodes by electrospinning. We studied here the effect of contact area between nanofibers and electrodes by controlling the surface roughness of electrode. PVDF sensors show increased piezoelectric responses with larger actual contact area of the interdigitated electrodes. The measured output voltage under periodic bending stress is up to about 1 V. It is expected that this facile method to fabricate the PVDF sensors can be used to integrate the energy harvesters into flexible and stretchable functional electronic devices.

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
