Coplanar waveguide techno TEMPO Oxidized Thermomechanical Pulp-Based Microwave Humidity Sensor
Bibliographic record
Abstract
The thermomechanical pulp (TMP) is a product of lignocellulosic biomass. This article investigates TEMPO oxidized TMP (TO-TMP) as an ecofriendly, low-cost, and highly sensitive dielectric material for humidity sensing applications. The TEMPO oxidation was used to increase the water absorption of TMP while overcoming the adverse hydrophobic effects imparted from lignin. The physical and the dielectric effects of TEMPO oxidation on a TMP sheet having a carboxyl rate of 80 mmol/kg were studied. An experimental validation with an original sensing scheme in frequency shift paradigm involving a microwave resonator in coplanar waveguide technology was proposed. In the 52%–75.3%RH range, the sensitivity rose from 7.76 MHz/%R to 9.04 MHz/%RH after the TEMPO oxidation increased the carboxyl content to 1164 mmol/kg, and to 12.1 MHz/%RH when the carboxyl content was enhanced up to 2233 mmol/kg. The effects of the TEMPO oxidation degree and the thickness variation are also studied.

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.
