Dynamic characteristics of a dielectric elastomer-based microbeam resonator with small vibration amplitude
Bibliographic record
Abstract
An analytical model is developed in the current work to analyze the dynamic characteristics of a dielectric elastomer (DE)-based microbeam resonator. The ambient pressure effect is taken into account by using the squeeze-film theory. Based on the Euler-Bernoulli beam model, approximate analytical solutions for the quality factor (Q-factor) and the resonant frequencies of the resonator have been derived using Raleigh's method for small amplitude vibration. The results indicate that the ambient pressure has significant effects on the Q-factor and the resonant frequency shift ratio, which represent the dynamic performance of the resonator. The active frequency tuning for such a resonator becomes feasible by changing the applied electrical voltage. It is found that high voltage is beneficial for improving the sensitivity of the resonator. However, high voltage may put the resonator at the risk of mechanical instability. The cut-off voltage for buckling has also been studied to predict the mechanical integrity of the resonator. This study is expected to be useful for design and applications of DE-based microresonators.

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.
