Printed Tattoo Electrodes for Electrophysiological Signal Acquisition
Bibliographic record
Abstract
The enhancement of medical tattoo electrodes over the past few decades have enabled them to serve as an alternative to conventional Ag/AgCl electrodes. Additive manufacturing methods can enable efficient and flexible fabrication of the tattoo electrodes, in contrast to the traditional fabrication methods demonstrated thus far. The objective of this project is to optimize printing methods to fabricate medical tattoo electrodes, as well as analyze and compare their performance both in vitro and in vivo to Ag/AgCl electrodes. Inkjet and extrusion printing methods were optimized to print various electrode patterns on a tattoo paper substrate and a simple contact platform was developed to allow for external connections to rigid components. Initial testing and analysis of the electrical and mechanical performance of the electrodes outside the human body was subsequently performed. The electrodes were ultimately tested on human subjects to acquire ECG and EMG signals, which were analyzed in terms of signal quality.

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; both teacher heads agree on what is shown here.
