Radio signals can be used to monitor your sleep patterns

The radio signal method has an 80 percent accuracy, which is comparable to the EEG system currently used in sleep clinics.

NSFW    CAMBRIDGE, MASSACHUSETTS — A team of researchers from MIT has developed a device that can monitor sleep patterns without attaching the patients to any sensors.

The device broadcasts radio frequency signals towards a person and researchers examine the signals reflected back to the receiver.

The captured radio signals are then studied by a deep learning algorithm which can determine the sleep stages of the person.

The system has an 80 percent accuracy, which is comparable to the EEG system currently used in sleep clinics, New Atlas reports.

"Our device allows you not only to remove all of these sensors that you put on the person, and make it a much better experience that can be done at home, it also makes the job of the doctor and the sleep technologist much easier," Dina Katabi, MIT professor of electrical engineering and computer science and leader of the study told New Atlas.

The researchers will conduct further studies on the impact of other diseases such as Parkinson's disease or Alzheimer's on sleep.
