Flexible Chemiresistive pH Sensor Based on Polyaniline / Carbon Nanotube Nanocomposite for IoT Applications
Bibliographic record
Abstract
This study presents a screen-printed and flexible chemiresistive pH sensor based on a nanocomposite of polyaniline emeraldine salt (PANI(ES)) and single-walled carbon nanotubes (SWCNTs). An optimized solution of SWCNTs/PANI(ES) (60/40 wt%) solution was drop-casted on top of flexible silver electrodes screen-printed on polyethylene terephthalate substrate. The sensor was annealed at an optimized temperature of 90 °C for 1 hour with a subsequent PANI(ES) drop_cast and annealing step. The developed chemiresistive pH sensor achieved high signal stability, sensitivity of 2.72 Ω/pH, linearity in the pH range of 2 – 10, and response times of 70 seconds. The pH’s sensitivity of the SWCNTs/PANI nanocomposite depends on the protonation/deprotonation process. The proposed sensor is an excellent candidate for smart medical bandage and wound monitoring applications.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
