Abstract
The present paper analyzes numerically and experimentally the dependence of the dynamic pull-in voltage amplitude on the values of externally-induced accelerations (e.g. Coriolis accelerations in the case of vibratory gyroscopes). We have investigated the nonlinear dynamic behavior on two different device types, a micro-gyroscope (A) and a micro-accelerometer (B), both fabricated in the SOI-MUMPs process (25 μm thick structural layer). Experimental measurements on the MEMS structures have been performed using Polytec MSA-500 equipment for analyzing the mechanical motion. They indicate that the dynamic pull-in voltages reduce from 100 V to 56 V for device A and from 21.77 V to 17.3 V for device B, for an equivalent acceleration of 0.319 ms-2, when the structures are actuated at their resonance frequency. If the induced acceleration is translated into an equivalent angular rate, _ equivalent, modulating the Coriolisinduced motion, the dynamic pull-in voltages vary from 57.612 V to 56.5 V for device A type and from 20.9 V to 10.75 V for device B type, for a change of 1 rad/s to 5 rad/s in _equivalent.

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.
