Frequently asked questions from XeThru users around the world.

What is Polysomnography and how does the XeThru sleep tracking sensor compare to it?

Polysomnography is a multi-parametric test used in the study of sleep and as a diagnostic tool in sleep medicine. It is considered the industry’s gold standard in sleep monitoring. Novelda conducted a comparison study with PSG and after over 92 hours of monitoring for 13 datasets, we can state that the sensor delivered comparable data to PSG in terms of movement and respiration readings. Details of the comparison can be found in our whitepaper.
