External defibrillation electrode conductive electrolyte dispersal pad

An external defibrillator system may include processing circuitry; signal generation circuitry communicatively coupled to the processing circuitry; and a plurality of electrodes, each including an electrode body electrically coupled to the signal generation circuitry and configured to deliver an electrical pulse therapy to a patient; and an electrolyte dispersal pad that includes a substrate defining a plurality of wells, each defining an opening; an electrolyte material, e.g., fluid, disposed within at least a portion of the plurality of wells; and a conductive material disposed over at least a portion of the openings and configured to retain the electrolyte material within the plurality of wells, where the processing circuitry is configured control the signal generation circuitry to pass a current pulse through a portion of the conductive material to fuse the portion of the conductive material to release the electrolyte material from at least one of the wells.
