1. A flexible, surface electromyographic electrode apparatus for use on a surface of biological tissue to measure bio-electric signals thereof, said electrode apparatus comprising:

  • a conductive signal electrode device having a signal contact adapted to directly contact the surface of the biological tissue to receive and transmit bio-electric signals, and a signal transmission portion electrically coupled to the signal contact;

    a conductive ground electrode device having a ground contact to adapted directly contact the surface of the biological tissue, and a ground transmission portion electrically coupled to the ground contact, said ground contact is disposed substantially about the signal contact so as to substantially surround a peripheral edge of the signal contact when both are in contact with the tissue surface; and

    an insulation washer device disposed between the signal contact and the ground contact to substantially prevent conductive contact therebetween.
