Validity of a non-contact sleep monitor

How accurate can it measure sleep?

A sleep monitor employing non-intrusive radar technology and machine learning can provide automatic sleep stage classification in healthy subjects.

The results show that the monitor can provide automatic sleep stage classification with a precision close to PSG in a sample of healthy, mostly young subjects.
