Electrodes conduct electrons from the electrotherapy device into the patient and serve as a conductor and medium between the two. The Dura-Stick Plus Self-Adhesive Electrodes is a premium version of electrodes because it has Permagel Hydrogel to serve as a superior coupling agent to minimize skin-electrode resistance.
Veristim Electrodes contain a uniquely coated silver carbon film for superior conductivity, eliminating "hot spots". This silver carbon film disperses the electrical current uniformly over the entire electrode surface. Pure copper lead wires with dispersive heads also help facilitate this superior dispersion.
