Sažetak
Surface electromyography (sEMG) electrodes are critical components for signal acquisition; their material properties directly dictate the stability and accuracy of the recorded signals. To address the limitations of traditional electrodes, such as poor flexibility and signal interference, this study prepared a gel electrode based on MXene/PEDOT:PSS/PAAm. Key properties, including conductivity, adhesion, and stretchability, were systematically analyzed. Results indicate that an optimal PEDOT:PSS to MXene ratio of 6:4 yields a composite conductive material with a sheet resistance as low as 10.3 Ω/sq. Performance tests demonstrated that the elec-trode's adhesion strength to porcine skin tissue reached (49.10 ± 1.25) kPa. Fur-thermore, its contact impedance with human skin was significantly lower than that of standard Ag/AgCl electrodes in the (0.1–1000) Hz frequency range. In sEMG acquisition experiments, compared to Ag/AgCl electrodes, the prepared electrode exhibited a higher signal-to-noise ratio (SNR), lower root mean square error (RMSE), a smoother signal waveform, and a more stable baseline. The elec-trode demonstrates excellent conductivity and adhesion, providing a high-performance solution for wearable sEMG monitoring equipment.
