EMG, EOG and ECG are biopotential sensors that measure the body's electrical activity.
EMG sensors measure the electrical activity of muscles. This information is used to diagnose muscle disorders, monitor muscle performance, and control prosthetic limbs.
EOG sensors measure the electrical activity of the eyes. This information is used to diagnose eye disorders, track eye movements, and control gaze-controlled interfaces.
ECG sensors measure the electrical activity of the heart. This information is used to diagnose heart conditions, monitor heart health, and check pacemakers.
