Flexible chemiresistive sensor with xurographically patterned gold leaf as contact electrodes for measuring free chlorine
Bibliographic record
Abstract
Free chlorine is commonly used for disinfecting water for various purposes including drinking water, recreational water etc. The free chlorine concentration should remain within a range of 0.5 -2 ppm for an effective disinfection specially for drinking water. Therefore, a low-cost sensor is required to measure free chlorine concentration at different position of the water distribution channels to ensure safe and healthy water for public. Here, we demonstrate a low cost, flexible and solid state chemiresistive sensor fabricated on a Kapton tape with Graphene like Carbon as the sensing film and xurographically patterned gold leaf as the contact electrode. The fabrication process is simple, quick and robust to manufacture reproducible electrodes. The chemiresistive sensor was able to measure free chlorine concentration from 0.05 -1.75 ppm.

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.
