Understanding the effect of carbon in carbon/salt/adhesive electrodes for surface electromyography measurements

摘要

Highlights ? In general, salt/adhesive (SA) electrodes are suitable to collect sEMG signals in a similar manner to carbon/salt/adhesive (CSA) electrodes. ? Correlation of sEMG signals between CSA and SA electrodes was high in time (≥0.87) and frequency (≥0.94) domain. ? CSA electrodes, which contain carbon in the adhesive layer, provide a better capability to manage motion, but are more susceptible to noise corruption and are less sensitive to myoelectric activity. ? SA electrodes, made without adding carbon to the adhesive layer, specifically a mixture with 15% salt, provided a better response to myoelectric activity and seem to be the most suitable alternative for sEMG data collection.
