Illustration of left eyelid sling that is attached to the electroactive polymer artificial muscle device (EPAM) after passing through an interpolation unit that is implanted in the lateral orbital wall (note screw fixation).  The power supply and artificial muscle are implanted in the temporal fossa. Conceptually, when the normal right eyelid blinks, the electrical sensor (green) sends a signal to the battery to activate the EPAM.
