The uncovered suggestion on the high-quality wire serves because the Energetic electrode. On account of this configuration, signals are generally more compact when recorded from a concentric electrode than when recorded from a monopolar electrode and they're a lot more proof against electrical artifacts from tissue and measurements tend to be to some degree extra reliable. Nonetheless, because the shaft is uncovered throughout its length, superficial muscle exercise can contaminate the recording of deeper muscles.
