SRC-DRI-001 Monitoring sleep, behavioural and environmental variables

The aim of this study is to validate new technologies designed to measure sleep and environmental variables (e.g. light and temperature) using a combination of wearable devices and sensors.  Such technology will allow us to unobtrusively and accurately record and monitor sleep-wake cycles and other health indicators over longer periods of time and may assist in the early detection of ill health conditions.

The Principal Investigator for this study is Professor Derk-Jan Dijk.
