The increased movement of eyes and eyelids is characteristic of the rapid eye movement (REM)
sleep stage, making it an important indicator in sleep monitoring. A device was designed
to detect this activity in a non-invasive way by means of measuring infrared light intensity
reflected off the eyelid. The system converts the light intensity into current through
a photodetector, performs analog signal processing and analog to digital conversion (ADC).
The data is transmitted wirelessly to a computer, where the results can be displayed, stored
and analyzed with a dedicated software, which also provides control over the device.
The hardware is embedded in a mask, which is put over the patient's eyes. User safety in terms
of mechanical, electrical and optical dangers has been ensured. The device was tested
on a napping subject.
