Electrooculography (EOG)

Purpose-built sensor for cortico-retinal standing potential activity measurement.

The biosignalsplux Electrooculography (EOG) sensor has been specially designed for seamless EOG data acquisition. Either used by itself or in combination with an eye tracker, our sensor can provide additional insight into your subjects’ eye gaze patterns.

The bipolar configuration, with two measurement electrodes, detects the electrical potentials in the specific temporal or facial region of choice, with respect to a reference electrode (placed in an area of low bioelectrical activity). The resulting signal is the amplified difference between these two leads, eliminating the common unwanted signals. Its convenient form factor enables a discrete application in the typical EOG electrode placement locations.
