Electrode units for sensing physiological electrical activity

摘要: Systems and apparatus for monitoring physiological electrical activity of an individual include a first electrode unit receiving signal indicative at location on body the second individual. Each units may be operated in field-sensing mode wherein is placed or proximity to individual's skin. The comprise capacitive sensor element, element each comprising electrodynamic which sensitive electromagnetic waves; antenna electrically conductive radiating waves. can either non-contact clothing contact directly
