Human brain has approximately a hundred billion neurons, which communicate with each other by sending electro-chemical signals. It is possible to measure these signals by placing electrodes on the surface of the skull. This method is called “electroencephalography” (or EEG) and the reading acquired from this process is brain waves.
Electroencephalography is the most commonly used method in labs to measure sleep. The Dreem headband uses the same method to measure brain activity during the night, and is thus able to precisely track sleep stages during the night.
