Dissolved Oxygen MEMS Sensor With Enhanced Sensing Current
Bibliographic record
Abstract
A new approach is proposed to enhance sensing amperometric current in three-electrode Clark dissolved oxygen (DO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) Microelectromechanical systems (MEMS) sensors. In the proposed approach, the counter electrode (CE) in a conventional concentric three-electrode sensor is modified to admit a large ratio of static electric current in an electrochemical solution. The typically large CE of a conventional sensor is replaced with an array of narrow-width electrodes. The modified CE is expected to reduce the inductive coupling and simultaneously increase the capacitive coupling of the structure. The overall changes of inductive and capacitive couplings are shown to enhance the sensing amperometric current of the sensor. Two μ-sensors are developed and fabricated based on MEMS technology including a conventional, as the reference and a new modified μ-sensors. The experimental results confirm an enhancement of 3.2:1 (0.352 μA:0.112 μA for 23% of DO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) in the sensing amperometric current of the developed MEMS μ-sensor compared to the conventional same-sized counterpart.

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.
