Korus: a Device to Prevent Sudden Unexpected Death in Epilepsy (SUDEP)
Study Details
Study Description
Brief Summary
The goal of this feasibility study is to test the Korus smart mattress in healthy volunteers.
The main questions it aims to answer are:
-
Can Korus accurately detect body position in bed (left, right, supine, prone)
-
Can Korus reposition the subject from a prone to recovery (sideways) position? Participants will be asked to lie down on Korus and turn into various positions; when the prone position is detected, they will be repositioned.

Detailed Description
Korus is a a smart mattress consisting entirely of pneumatically inflatable smartcells with embedded sensors. It is designed to detect a subject's body position an inflate the proper smartcells to reposition a subject from the prone to the recovery (sideways) position. Healthy control subjects will be recruited to test Korus' sensing system and its performance in repositioning the subject. Korus will utilize specialized sensors and a computer learning algorithm to detect the subject's body position. Based on this data, Korus will activate the appropriate smart cells to reposition the subject.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Control subjects The subject will lie down on the Korus smart mattress. Korus will detect when the subject is in a prone (face-down) position and reposition the subject into a recovery (sideways) position. |
Device: Control subjects
The subject will be repositioned from the prone to recovery position

Outcome Measures
Primary Outcome Measures
- Body position detection [5 seconds]
Correct detection of one of 4 cardinal body positions: prone, supine, left, right
- Number of subjects correctly repositioned from the prone to recovery position [30 seconds]
We will measure the performance of Korus to successfully reposition the subject from the prone to recovery position
