1. A Bio-electrode with a biocompatible electrode-to-body interface surface layer providing a body-directed surface, said surface layer having on the basis of a dc analysis a bulk resistivity, as measured in a direction across said surface layer, parallel to the plane of said surface, ranging from 2×

  • 10 exp 5 to 10 exp 11 ohm-centimeters and having a reduced tendency for polarization to be formed within an electrolyte layer when present at the electrode-to-body interface and thereby reducing polarization noise.
