Electrode apparatus for non-invasively applying electrical stimulation to a human body portion via a skin interface. The apparatus comprises an electrode module 46 having an end 54 for defining an electrolyte application region between the module and the skin and a plurality of spaced apart electrodes that are electrically contactable to the skin via an electrolyte. Apparatus further comprises a controller configured to individually adjust electrical signals across or between each of the electrodes and each of one or more pairing electrodes. The controller may determine: a spatial distribution of current flow within the electrolyte; an impedance or resistance of a sub-region of the electrolyte application region; an impedance model of the body portion. The controller may selectively dispense electrolyte from a reservoir and/or remove electrolyte from the application region. The apparatus may comprise: an electrolyte containment for restricting leakage; one or more sensors to measure one or more physiological stress indicators. Another electrode module with one or more electrodes and one or more shunt measurement conductors between electrodes. Also a method of estimating a dosage of electrical stimulation impinging on a target treatment region internal to a human body portion by determining an electrical field through the body portion. |
