Flexible conductive polymer electrodes for applications in tissue Electrical Impedance Scanning (EIS)
Bibliographic record
Abstract
Electrical Impedance Scanning (EIS) is a potential alternative for breast cancer screening, and has been investigated as a breast cancer screening tool since the 1920s. However, it has not become a regular diagnostic tool due to limitations such as low spatial resolution, poor electrode design, and mechanical skin contact issues. In this thesis, we attempt to address these limitations through development and demonstration of a novel flexible conductive nanoparticle composite polymer (C-NCP) electrode array. The array is fabricated using a new multi-level soft lithography. The array is highly flexible, resulting in improved skin contact and easy conformability to curved surfaces. Flexible Ag/AgCl electrodes (average resistivity of 1.75x10-3 +/- 14.3% ohm-m) and Ag/graphene electrodes (average resistivity of 4.45x10-4 +/- 18.7% ohm-m) are fabricated and tested on a tissue phantom and animal flesh. The results are presented in Cole-Cole plot format for easy comparison between regular tissue and tissue with introduced anomalies.

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.
