Abstract
A gel-supported lipid bilayer formed at the base of an artificial hair is used as the transduction element in an artificial, membrane-based hair cell sensor inspired by the structure and function of mammalian hair cells. This paper describes the initial fabrication and characterization of a bioderived, soft-material alternative to previous artificial hair cells that used the transduction properties of synthetic materials for flow and touch sensing. Under an applied air flow, the artificial hair structure vibrates, triggering a picoamp-level electrical current across the lipid bilayer. Experimental analysis of this mechanoelectrical transduction process supports the hypothesis that the current is produced by a time-varying change in the capacitance of the membrane caused by the vibration of the hair. Specifically, frequency analysis of both the motion of the hair and the measured current show that both phenomena occur at similar frequencies (0.1–1.0 kHz), which suggests that changes in capacitance occur as a result of membrane bending during excitation. In this paper, the bilayer-based hair cell sensor is experimentally characterized to understand the effects of transmembrane potential, the applied air flow, and the dimensions of the hair.

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
