ABSTRACT:
An electrode for collecting surface electromyographic (EMG) signals consists of a generally bolt-shaped structure having a circular signal-gathering head and an integral shaft for support purposes and for transmission of electrical signals. The head of the electrode is configured as a disc having a plurality of pyramids distributed substantially evenly over the signal gathering surface with the tips of the pyramids projecting outwardly of the head for contact with the skin of a patient. Preferably, the electrode consists entirely of 316L stainless steel, the pyramids are formed by grinding or electromachining and the shaft is threaded for receipt of a clamp nut. The electrode is adapted for mounting in a hole in a thin, flexible support member by means of the shaft to maintain spacing among adjacent electrodes and to assure proper contact with the patient.
