V-Watch S.A. is developing a software platform that could enable sleep monitoring in clinical trials in a more natural environment, for a much longer period and at a fraction of the cost of laboratory polysomnography.

Laboratory polysomnography is the gold standard for monitoring sleep in clinical trials. The technique monitors brain activity via electroencephalography, eye movement via electrooculography and neuromuscular activity via electromyography to determine sleep architecture. Sleep architecture describes the pattern of different stages of non-rapid eye movement and rapid eye movement sleep in a session of sleep.
