Abstract
La présente invention concerne une électrode biologique destinée à détecter des signaux cardiaques et d'autres éléments similaires qui comprend une surface d'électrode sèche possédant une résistivité élevée de façon à réduire l'effet du bruit de polarisation. Cette électrode est combinée avec un circuit qui possède une résistance de décharge externe à travers laquelle on obtient un signal d'entrée, cette résistance de décharge possédant une valeur qui abaisse la constante de temps du bruit de polarisation en dessous de une seconde.
