Design and Analysis of Planar and Lattice-Electrostatic Comb Drive Actuators
Bibliographic record
Abstract
This paper presents an analysis of the electrostatic forces that act on a laterally driven comb drive actuator, in order to provide a clear understanding of the actuator geometry and its effects on system performance. Contrary to more familiar models, we provide a proper breakdown of the forces acting on a lateral comb drive structure by examining the electric field induced in a single actuator finger. Our results demonstrate the asymmetric nature of the forces, and its consequences. To counter these effects, we propose a novel actuator design which employs an out-of-plane interdigitated comb lattice. The simulation results comparing the new lattice design to the traditional planar comb drive actuator reveal a 66% increase in lateral actuation force, a 40% increase in change in capacitance per unit displacement, in addition to superior rectilinear stability under torsional forces.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
