Flexible neural microelectrode arrays reinforced with embedded metallic micro-needles
Bibliographic record
Abstract
Neural microprobes with 16 stimulation/recording channels are fabricated employing surface micromachining techniques. Each device integrates a flexible polyimide-based interconnection cable, the array of bonding pads, and 4 parallel shanks hosting the electrode sites, all constructed in a single 3 mask fabrication process. In order to provide the shanks with enough mechanical strength for insertion into the tissue, a 15 μm thick gold micro-needle is embedded inside each shank as the reinforcement structure. A polyimide shell encapsulates the micro-needles from electrode sites and the interconnection lines. The shanks are 4 mm long, 100 μm wide at the base, and 24 μm thick. The electrode sites measuring 20 μm × 20 μm are addressed through gold interconnection lines to reduce the electrodes impedances and consequently improve the signal to noise ratio of the recording signal. This paper presents the details of microprobe fabrication and the preliminary characterization results.

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.
