An electrode configured for use in a direct current electrical stimulation system, which includes a control circuit configured to provide a stimulating current, includes a main body and a plurality of pin members. The main body is electrically coupled to the control circuit to receive the stimulating current therefrom and includes a base wall and a surrounding wall cooperating with the base wall to define a receiving space for receiving an electrically conductive liquid. The pin members extend from the main body, are in fluid communication with the receiving space, and permit delivery of the electrically conductive liquid to a subject when the pin members are placed in direct contact with the subject.
