Abstract
Organic electrochemical transistors (OECTs) based on poly(3,4-ethylenedioxythiophene) (PEDOT) have been extensively studied, yet devices fabricated via electropolymerization remain underexplored in terms of the underlying ionic dynamics and the potential for flexible integration. In this work, we demonstrate robust OECTs based on electropolymerized PEDOT, exhibiting negligible drain current degradation after 1000 cycles of operation in aqueous NaCl. Compared to inkjet-printed devices, they offer markedly superior cycling stability, which is further enhanced by the incorporation of the small anionic dopant ClO 4 − . We also show flexible, lightweight OECTs by electropolymerizing PEDOT on ultrathin parylene substrates, achieving stable performance under mechanical strain. Furthermore, Electrochemical Quartz Crystal Microbalance with Dissipation (EQCM-D) analysis reveals distinct ion transport behavior in PEDOT:ClO 4 , where dopant ejection dominates doping/dedoping process, unlike in PEDOT:PSS. This study underscores the advantages of electropolymerization and small-ion doping, offering new mechanistic insights and advancing the design of high-performance, flexible OECTs for bioelectronic applications.

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 it
