Learning Sleep From Wireless Signal


What if WiFi can tell when you are dreaming? Dreaming is a biological phenomenon associated with certain brain activities Brain activities change and enter different stages during sleep such as awake, light sleep, deep sleep and rapid eye movement or REM Each stage has its own functions dreams mainly during REM deep sleep for memory consolidation and light sleep for cognitive processing Today, monitoring sleep is done in the hospital with many sensors It requires the person to wear them all over their body and spend the night like that Making it hard to actually sleep. in contrast, a new MIT technology monitors your sleep without any on-body sensors The person can sleep comfortably at home while the device sits in the background and transmits a low-power radio signal to predict the sleep stage So how does it work? It uses an advanced AI algorithm Which takes the radio signal as input and feeds it into a new deep neural network and outputs sleep stages It’s accuracy is comparable to the accuracy of a sleep technician, which is about 80% Diseases like many sleep disorders, Alzheimer’s, Parkinson’s disease and Depression all interact with sleep stages Researchers believe that the MIT technology can help doctors better understand those diseases and improve treatment

  1. This would work very well for lucid dream induction. When recognizing rem sleep the user can be signaled within dream by something as simple as a flashing room light and some future devices in development will do cranial stimulation when detecting REM sleep. But your device would be much more comfortable and reliable. Is there a way i can buy or build a version of your device? Great work.
