A device to find out the disturbance during sleep

Many of us will have the habit of disturbed sleep especially during night time either by having dream or by some sort of disturbances. In fact we cannot judge how many times that we woke up during last night sleep. Now the scientists of startup headquartered in Newton came up with the device that will monitor during entire night and track the sleep cycles. Thus it will help the user in improving their sleep but it is not a medical device to predict sleeping disorders. The device is nothing but a small headband that will record our entire sleep cycles to identify the disturbances.
