Dry electrodes

A method of preparing a dry electrode comprising:

• preparing a precursor sheet article, wherein preparing the precursor sheet article comprises:
• providing a substrate with a first major surface or a second major surface;
• providing electrically conductive particles, wherein the electrically conductive particles comprise shaped particles with at least one point;
• contacting at least one electrically conductive particle with the second major surface of the substrate such that the at least one point protrudes from the second major surface of the substrate;
• providing a layer of supporting material with a first major surface and a second major surface;
• contacting the first major surface of the layer of supporting material to the second major surface of the substrate and the electrically conductive particles, such that the at least one point of at least one electrically conductive particle protrudes through the second major surface of the layer of supporting material.
