Experimental Investigation of Squeezed MRF Film Stopper and Its Effect on Vibrating Bimorph for Frequency Tuning of an Energy Generator
Bibliographic record
Abstract
This paper proposed a frequency tuning concept using magnetorheological fluids (MRF) in squeeze mode as a stopper. The MRF is a smart fluid that changes from a liquid state into a semi-solid state within milliseconds when a magnetic field is applied. The change from liquid state to semisolid state demonstrated in this study is achieved by varying the distance between two magnets and hence the magnetic field. The experimental results show that the frequency of the vibrational system was increased by 16% when the MRF was activated at 0.1T. The damping was also increased by 48.8% when a magnetic field of 0.3T was added to MRF. The change in damping also affected the stiffness of the piezoelectric cantilever beam and hence the power generated from the piezoelectric bimorph cantilever. The generated power from the cantilever without MRF damping was calculated to be 1.1 μW at a resistance of 330 kΩ but increased to 9 μW when the damping of 0.1T was applied.

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.
