Suggestion for optimal location of textile-based ECG electrodes on an elastic shirts considering clothing pressure of the shirt

For an effective design of ECG shirt, clothing pressure in each point with a shirt composed of 60% polyester, 33% cotton, and 7% Lycra was measured, and the qualities of ECG signals with the textile-based electrodes on the shirts according to contact capacity were compared. A clothing pressure measuring device developed for stationary state was used in the experiment to quantitatively analyze clothing pressure, and the ECG signal detection rates of the textile-based electrodes according to the regions where they were attached were calculated. Five subjects were participated in the experiments, and their clothing pressures were measured in 30 points in their upper body in 3 postures. The results showed a high degree of correlation between clothing pressure and ECG signal detection rate regardless of the subject´s postures.
