10 sie 2017 · The device transmits RF waves at one-thousandth the power of Wi-Fi signals and picks up signals reflected from walls, furniture, and sleeping subjects, whose tiniest movements change the frequency of the reflected signal.
6 sie 2017 · To make it easier to diagnose and study sleep problems, researchers at MIT and Massachusetts General Hospital have devised a new way to monitor sleep stages without sensors attached to the body.
6 sie 2017 · Their sensor uses low-power radio waves that detect small changes in body movement caused by the patient’s breathing and pulse, then translates those measurements into sleep stages: light, deep, or rapid eye movement (REM).
13 wrz 2017 · This was done by showing it many examples of sleep stage data from an FDA-approved monitoring device, while it tracked radio frequency signals in a room. As radio waves reflect off a...
7 sie 2017 · To make it easier to diagnose and study sleep problems, researchers at MIT and Massachusetts General Hospital (MGH) have devised a way to monitor sleep stages without sensors attached to the body.
Researchers at MIT and Massachusetts General Hospital have created a new device to monitor sleep stages without having to attach sensors to the body. Typically diagnosing and tracking sleep issues involves attaching electrodes and many other sensors to the patient, further disrupting sleep.
20 gru 2019 · • Sleep hypnograms generated by the AI model solely from radio waves have an average accuracy of 81.6% and a standard deviation of 7.9%. Accurate sleep metrics are extracted from radio waves including sleep efficiency (r=0.93, p<0.001), total sleep time (r=0.91, p<0.001), sleep latency (r=0.83, p<0.001), and wake after sleep onset (WASO) (r=0.89,
