Sono is a project with the intent on creating a wearable that can be used before, during, or after traveling. It uses a revolutionary electrothermal heating film that adjusts its temperature according to a user's needs. Sono also aids in canceling out distracting stimuli such as light and sound which allows the user to fall and stay asleep more easily. With its cooling, heating, and haptic features, Sono can discreetly help travelers rest peacefully and gradually wake up during a flight to help synchronize their circadian rhythm to the correct time zone while traveling.
