Muse S Athena: the headband that reads your thoughts and knows when to wake you up

The trauma of waking up is a common experience: that feeling of grogginess, known as sleep inertia, that accompanies us when we are abruptly pulled from deep rest.

Muse, a Canadian company leading in applied neuroscientific technologies for consumption, has decided to launch Smart Wakeup, a function aimed at revolutionizing our morning approach based on clinical data from the electroencephalogram (EEG).

Muse S Athena and "scientific" waking: when the alarm reads brain waves

The core of this innovation is the Muse S Athena headband, a device that does not just count steps or monitor heart rate but acts as a true portable neuroscience laboratory. Unlike common smartwatches, which deduce sleep phases through predictive algorithms, the Athena uses seven EEG sensors to map real-time electrical activity in the brain.

The new Smart Wakeup function operates within a customizable "wake-up window," usually between 30 to 60 minutes. During this interval, the device constantly monitors brain waves; as soon as it detects a transition to a phase of light sleep, it starts a gradual audio sequence to bring the user back to wakefulness in the most natural way possible. If the ideal phase is not detected by the maximum time limit, the alarm will still ring at the set time, ensuring punctuality.

Muse's approach is not just theoretical. The development of Smart Wakeup is based on an internal study conducted on over 6,200 nights of sleep and 1,300 users. The collected data confirmed a direct link between waking during light sleep and a significant improvement in morning mood. It's interesting to note how the company emphasizes that the technology does not replace good habits: the greatest benefit was observed in individuals who maintain high sleep efficiency and at least seven hours of rest.

From a technical standpoint, Muse S Athena also integrates PPG sensors for heart rate, an accelerometer for breath, and a gyroscope for posture. The real challenge, however, remains ergonomics: wearing a textile band around the head at night is a different experience compared to a ring or a watch, but it's the price to pay for data accuracy that approaches that of sleep laboratories.

The rollout of the function will begin on April 15 (or August 15 depending on geographical areas) and will be reserved for Muse Premium users. This is perhaps the only real "hurdle" for the end user: in addition to purchasing the hardware (priced high at about 450 euros), the function requires a monthly subscription to unlock the entire analysis ecosystem, which also includes the Deep Sleep Boost to enhance the quality of deep sleep through synchronized sound stimuli.
