Patent ID: 6845272

Claim:
A defibrillation or electrocardiogram electrode for establishing electrical contact with the skin, said electrode comprising an electrically conductive metallic layer having a high sensitivity to acid and an electrically conductive gel attached to said metallic layer, thereby providing an interface between said gel and said metallic layer, wherein said electrically conductive gel has a pH between 1 and 3 so as to provide corrosion of said metallic layer, wherein a high concentration of ions are etched from said metallic layer, generating a concentration of metallic ions at the interface between the gel and said metallic layer, said concentration of metallic ions contributing to the availability of current carriers when a current is impressed on the electrode, and wherein said defibrillation or electrocardiogram electrode is adapted for administering an electric shock to a patient or monitoring the electrocardiogram of said patient when connected to a defibrillator or an electrocardiogram apparatus.
