Getting a good night’s sleep is a universal desire for the human race. At the Consumer Electronics Show today, UrgoNight showed off its non-invasive solution to train your brain to sleep better. It’s designed to teach your brain to sleep better using electroencephalogram (EEG) measurements and app-based brain exercises.

UrgoNight requires you to wear the device for 20 minutes a day, three times a week for three months. It uses positive feedback to show you what brain processes and mental activities work best to produce the brainwaves associated with better sleep.
