Abstract
Abstract This paper describes a reliable, repeatable, and cost effective solution for fabrication of complex mechanically reconfigurable microfluidic devices for soft electronics. The devices are made of eutectic gallium indium (EGaIn) in styrene‐ethylene‐butylene‐styrene thermoplastic elastomer with gecko‐adhesive based bonding which both aids in sealing thin channels and directing flow of high surface energy metal into small channels in a repeatable process. Selective filling of complex microfluidic structures is achieved by controlled advancement of EGaIn‐air interface using optimized hydrophobic valves. These valves are designed based on EGaIn's critical Laplace pressure to fabricate variable aspect ratio and multilayer features or designs with multiple branches and arrays of isolated elements. As a proof of concept, different antennas (bow‐tie, folded and multilayer dipoles, and microstrip patch antennas) and a hybrid power divider are fabricated with total device thicknesses less than 600 µm. These devices can conform to complex surfaces for applications like body worn sensors, and can be stretched or bent to change their electromagnetic properties such as center frequency, bandwidth, and impedance matching.

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 it
