We recently proposed a novel Clean Unit System Platform (CUSP) to establish a dust-/microbe-free environment for various purposes. Tent-type CUSP enables us to detect fluctuation of air-borne particles as bio-kinetic signals reflecting body movements during sleep, which we designated as “kinetosomnogram” (KSG).
We validated air-cleansing capacity of the tent CUSP and recorded changes in particle counts in response to various body movements. A volunteer with a polysomnography (PSG) equipment stayed in the tent CUSP overnight to record a KSG. The KSG was compared with PSG parameters. Each surge in the KSG appeared to have a corresponding arousal response (stage W) in the PSG. Moreover, there was a significant peak of power spectral density at 80-100 minutes suggestive of REM periods. The tent CUSP provides us with ultraclean environment for sleep and may be of help to assess sleep quality in a non-invasive and non-contact manner.
