VOC detection using an all polymer flexural plate wave sensor
Bibliographic record
Abstract
We have developed an all-polymer, micro-inkjet printed, flexural plate wave (FPW) sensor for toluene vapor detection. The sensor consists of a piezoelectric polyvinylidene fluoride (PVDF) substrate with conductive polyethylenedioxythiophene polystyrene sulfonate (PEDOT:PSS) interdigitated transducers (IDTs) and a polymer sensing layer coating for selective absorption of a targeted analyte. Sensor performance is investigated by exposing polyvinyl acetate (PVAc) and polystyrene (PS) sensing layers to varying concentrations of toluene vapor. The resulting frequency shift, due to mass loading, expansion and softening of the sensing layers, is compared with predictions using a semi empirical model. In this work, Flory-Huggins solution theory is used to predict the mechanical response of the sensing layers to solvent vapor concentrations.

How this classification was reachedexpand
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.
