EMG 전극소재로 적합한 전도성 원단 성능 및 안정성 평가

초록

Since the pandemic, there have been ongoing research studies on EMG textile electrodes as people's exercise spaces have changed. However, electrodes require high pressure during exercise, and incomplete compression during exercise necessitates research on materials. In this study, we investigated the correlation between the properties of conductive fabrics suitable for the stability and performance of dry textile electrodes. We examined the properties of five types of conductive fabrics, fabricated and attached electrodes, and placed EMG sensors on the biceps according to the SENIAM guidelines to obtain signals. We also demonstrated the correlation between the stability of the signal and the stiffness of the fabric, showing that there is an association with the modulus of the fabric. The results showed that a higher modulus led to lower SNR standard deviation, indicating better performance stability, while a lower resistance resulted in a higher SNR mean, indicating improved performance of the conductive fabric. The study revealed the correlation between the properties of conductive fabrics and EMG performance, demonstrating the ability to design suitable fabrics for textile electrodes.
