0-3 Barium Titanate-PDMS Flexible Film for Tactile Sensing
Bibliographic record
Abstract
Lead free BaTiO3-PDMS piezoelectric composite thin films are fabricated with simple process. Composite films are prepared by dispersing 20, 30, 40, and 50 wt% of BaTiO3in cross-linked PDMS matrix. Corona poling of the films is performed to improve the piezoelectric properties of the films. Piezoelectric properties of the films are studied by measuring the charge developed across the thickness of the film under a compressive force. A 50 wt% poled BaTiO3-PDMS film has shown a piezoelectric charge constant of 178 pC/N and achieves a dielectric constant of 4.59. Tensile tests indicate that these films are very soft and flexible with low Young’s modulus. A 50 wt % poled BaTiO3-PDMS film film has shown a Young’s modulus 3.92 Mpa. The film generates charge across the film proportional to the finger pressure applied on them. Thus it demonstrates effectiveness for tactile sensing. As a tactile sensor a 50 wt% poled film shows a sensitivity of 38.34 kPa−1. High charge response for tiny forces makes the composite a good candidate for tactile sensing applications such as robotic skin and touch pads.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
