Abstract
A novel flexible free-standing infrared graphene-based photothermoelectric detector has been designed and fabricated without any substrate support. The integration of polymers with nanomaterials has significantly enhanced the compatibility of multi-functional detection technologies. By combining graphene with poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS) polymer to form composites, the final photodetectors have performed high flexibility with bending treatments. The signal under blackbody infrared source radiation has been collected and compared across different graphene loadings, where 10 wt% loading of graphene achieved the highest photoresponsivity under peak wavelength at 4.3 micrometer within 6 seconds response time. It achieves maximum 2.27 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$mV/W$</tex-math></inline-formula> photoresponsivity with 6.95 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$ \times {10^5}\;cm \cdot H{z^{1/2}}/W$</tex-math></inline-formula> detectivity, which is 5 times higher than pure PEDOT: PSS-based detector. These findings provide valuable insights for advancing graphene-based composites in real-time infrared detection applications.

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 it
