Abstract
Rapid Eye Movement (REM) sleep is responsible for the long-term memory restorative process and enhances the prefrontal cortex’s ability to filter unwanted thoughts, making abnormalities in REM sleep strong indicators of developing unhealthy habits, and even sleep disorders. Current sleep tracking devices, such as polysomnography (PSG), are expensive, ranging from $500 to more than $10,000. Products such as Oura Ring are cheaper, but less accurate. To provide a more affordable, accurate, and comfortable alternative, a low-cost preliminary screening REM sleep mask was developed based on eye movement detection. This device produces a personalized sleep report that includes the number of REM groups, start/end time, REM duration, etc. Validation in a simulated environment demonstrates the device’s ability to differentiate between motion and non-motion. Furthermore, preliminary results from overnight sleep tests show promising results.
