Microfabricated EHD Pumps With High Aspect Ratio Electrodes
Bibliographic record
Abstract
This work presents the design, fabrication and testing of electrohydrodynamic (EHD) micropumps with three dimensional (3-D) electrodes. It is known that the body force on the fluid due to an electric field is increased by increased injection of charges. In this design, 3-D micro pillars are used electrodes to provide high electrode-fluid contact area and to improve charge injection. Three different electrode designs were used to investigate the effect of different parameters, such as electrode spacing and pillars size, on the pump performance. The electrodes were fabricated using nickel, and were integrated into a microchannel of dimensions 22mm × 5mm × 100μm. The micropumps were tested under a no-flow condition with ethanol as the working fluid. The preliminary results suggest that the new 3-D electrodes improve pump performance over pumps with 2-D planar electrodes. A maximum pressure head of 780 Pa was achieved at an applied voltage of 150 V with the 3-D electrodes.

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.
