Electrooculogram (EOG)

Wearable Sensing’s 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

*Actual EOG data collected from DSI-24


EOG, or Electrooculography, is a technique for measuring the corneo-retinal standing potential that exists between the front and the back of the human eye. Electrodes are typically placed above and below the eyes, or to the left are right of the eyes. EOG is primarily used to detect the movement of the eye. Using EOG sensors can help correlate eye movement artifact that occurs in EEG signals, and thus assist in the rejection of such eye movement artifacts.

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

Compatible DSI Systems

DSI Flex

The DSI Flex has 7 customizable sensor locations, which can be configured in any variation of ExG, GSR, RESP, and TEMP


The DSI-24 has 3 auxiliary inputs on the headset, allowing seamless integration of wired ExG, GSR, RESP, and TEMP
