Wearable technologies and textile-based electrodes have emerged as promising alternatives to conventional gel-based Ag/AgCl electrodes for surface electromyography (sEMG) monitoring, particularly in long-term and daily-life applications. In this study, a specially designed sEMG acquisition hardware was combined with a smart garment in form of leggings containing conductive fabric electrodes. The performance of textile-based electrodes was evaluated, and their verification was conducted by comparing the sEMG signals acquired from gel-based Ag/AgCl electrodes and textile-based electrodes through paired t-test analyses for both maximum and minimum amplitude values. Verification of the developed hardware was carried out with the BIOPAC Student Lab sEMG device. The results demonstrated no statistically significant differences across any measurement regions (p > 0.05), and the mean differences remained minimal with confidence intervals consistently spanning zero. These findings confirm that the textile-based electrodes provide signal quality and measurement stability comparable to conventional electrodes (gel-based Ag/AgCl). Overall, the developed wearable platform offers a reliable, comfortable, and reusable solution for sEMG monitoring, supporting its suitability for future applications in sports performance, rehabilitation, and continuous physiological tracking.
