Abstract

fetched live from OpenAlex

In this thesis a novel automated micro assembly mechanism is developed. The assembly mechanism utilizes repulsive-force actuators to flip surface-micromachined 2D structures out-of-plane and assemble them into 3D micro devices. The novel micro assembly mechanism is suitable for wafer-level multi-devices batch assembly without external interference. It can assemble 2D structures not only at the vertical position (perpendicular to the substrate) but also at positions at any angle to the substrate. Two approaches, i.e., graphic method and analytical method, are proposed for designing the micro assembly mechanism. Prototypes are fabricated using the PolyMUMPs surface micromachining technology and tested. The experimental results verify the concept of the novel automated micro assembly mechanism. The strength of the assembled 3D structures in terms of withstanding external acceleration is calculated. The calculated result well matches the experimental result which is about 7g. Using the micro assembly mechanism, 1D and 2D rotation micromirrors are designed for various applications.

Full frame distilled prediction

Teacher imitation

Not 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.
