Abstract
A pressure sensor functionalised with vertically aligned carbon nanotubes is presented. The sensor is fabricated to have a multi-walled carbon-nanotube forest supported by a deflectable 8 µm-thick Parylene-C membrane that is suspended by the silicon frame. The responses of the fabricated sensors are experimentally characterised. The sensitivities to positive and negative gauge pressures are found to be comparable in magnitude with the average values of −986 and +816 ppm/kPa, respectively. The measurement also reveals that the temperature coefficient of resistance for the forest suspended with the Parylene membrane is −515 ppm/°C and ∼3× smaller than that for the forest fixed onto the silicon substrate.

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
