The device includes an electrode for applying an electrical stimulation and a gel or liquid dispensing system. The electrode is attached to a first side of a garment such that a surface of the electrode is placed in contact with a portion of a user's skin when the garment is worn by the user. The gel or liquid dispensing system is attached to the garment and configured to be actuatable to dispense a gel or liquid onto the surface of the electrode, the dispensing system having a reservoir configured to hold the gel or liquid and a fluid passageway extending from the reservoir to the surface of the electrode. The electrode may be a carbon or carbon equivalent electrode. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The device of claim 1, wherein the dispensing system is attached to the second side of the garment, the second side opposite the first side, and wherein the fluid passageway extends through an opening in the garment. ### Claim 3 (depends on 1) The device of claim 1, further comprising a valve positioned in the fluid passageway. ### Claim 4 (depends on 3) The device of claim 3, wherein the valve is a one-way valve configured to allow the gel or liquid to flow in only a direction from the reservoir to the electrode. ### Claim 5 (depends on 1) The device of claim 1, wherein the reservoir is refillable. ### Claim 6 (depends on 5) The device of claim 5, wherein the reservoir further comprises an inlet port configured for refilling the reservoir. ### Claim 7 (depends on 6) The device of claim 6, wherein the reservoir is configured to receive pre-filled packets of the gel or liquid. ### Claim 8 (depends on 1) The device of claim 1, wherein the reservoir is selectively attachable to the garment. ### Claim 9 (depends on 1) The device of claim 1, wherein the electrode comprises carbon. ### Claim 10 (depends on 1) The device of claim 1, wherein the pressure deformable material comprises a thin plastic material. ### Claim 11 (depends on 1) The device of claim 1, wherein the pressure deformable material comprises a rubber material. ### Claim 12 (depends on 1) The device of claim 1, where the electrode comprises carbon. ### Claim 13 (depends on 1) The device of claim 1, wherein the electrode comprises a carbon equivalent. ### Claim 14 (depends on 1) The device of claim 1, wherein the reservoir is further configured to receive a pre-filled packet of gel or liquid, the reservoir further comprising: a base portion, a movable portion attached to the base portion by a hinge and configured to move between an open position and a closed position, in the closed position the movable portion and the base portion defining an interior volume, a port positioned within the interior volume and configured to mate with a corresponding port on the packet, and wherein the movable portion includes the deformable material, and wherein the dispensing system is configured to be actuated by applying pressure to the deformable material.
