    • Contact-free radar recordings of body movement can reflect ultradian dynamics of sleep 

      Heglum, Hanne Siri Amdahl; Drews, Henning Johannes; Kallestad, Håvard; Vethe, Daniel; Langsrud, Knut; Sand, Trond; Engstrøm, Morten (Peer reviewed; Journal article, 2022)
      This work aimed to evaluate if a contact-free radar sensor can be used to observe ultradian patterns in sleep physiology, by way of a data processing tool known as Locomotor Inactivity During Sleep (LIDS). LIDS was designed ...
