1. A modular waterproof therapeutic electrode component for preventing water ingress and for servicing, comprising:
a substrate comprising a conductive surface,
a reservoir of conductive fluid mounted on the substrate,
a reusable waterproof enclosure comprising circuitry, the reusable waterproof enclosure configured to be removably coupled to the substrate;
a gas cartridge in electrical communication with the circuitry and mounted on the substrate, the gas cartridge configured to cause the reservoir to release the conductive fluid onto the conductive surface to reduce electrical impedance between the conductive surface and skin of a subject; and
a mounting plate disposed on an upper surface of the substrate, the mounting plate providing a conduction path for high voltage electrical therapy from the circuitry to the conductive surface.
