DSI – EOG 

(Electrooculogram)

DSI EOG are dry electrode sensors that have a wired connection directly to the DSI-24, DSI-7, or DSI Flex system. The sensors are placed on the face, near the eyes, and are used to detect the electrical activity of the eye. 

EOG is a measure of the electrical field of the moving eye.

DSI electrode types

Wet electrodes

DSI EOG can be equipped with snap-on sticky electrodes that can be easily placed anywhere on the face.

Dry electrodes

DSI EOG can be equipped with snap-on dry electrodes that can be secured on the face with tape.
