Gel dispenser for electrodes

A device for electrical stimulation of a user, the device comprising:

• an electrode having a first side attached to a first side of a garment and having a second side, opposite the first side for contacting a portion of a user's skin when the garment is worn by the user, wherein the electrode comprises surface features, formed on the second side of the electrode to distribute a gel or liquid across the surface of the electrode;
• and
• a gel or liquid dispensing system attached to the garment and configured to be actuatable to dispense a gel or liquid onto the second side of the electrode, the dispensing system comprising
• a reservoir configured to hold the gel or liquid, the reservoir having a compressible bubble shaped surface positioned on a second side of the garment directly opposite the electrode, the bubble shaped surface of the reservoir comprising a pressure deformable material extending away from the second side of the garment;
• and
• a fluid passageway extending straight from the reservoir through the garment and through the electrode to the second side of the electrode, wherein the reservoir and the fluid passageway are collectively configured to deliver the gel or liquid through the passageway and onto the second side of the electrode when the bubble shaped surface of the reservoir is deformed.
