Monitoring sleep patterns usually involves a hydra of sensors that keep track of brain activity, muscle movements and heart rates, but a startup called Nyx Devices has developed a new night shirt that can evaluate the quality of a user's slumber by analyzing only breathing patterns. The form-fitting Somnus Sleep Shirt is embedded with two sensors that keep track of a person's overnight breathing and transmit this information to a small data recorder, which slides into the lower corner of the nightie. When a user wakes up, he or she can upload their stats to Nyx's website, where they can generate more detailed analytics and log their caffeine and alcohol intake to find out how all those martini lunches affect their snoozing. Co-inventor Matt Bianchi, a sleep neurologist at Massachusetts General Hospital, thinks the Somnus could help patients suffering from insomnia, who often have difficulty determining how much shuteye they actually get. It's worth noting, though, that this exclusively respiratory approach is still considered experimental and Nyx still has to conduct a few at-home tests before bringing the shirt to market next year, hopefully for less than $100. Until then, we'll just keep tossing and turning in our Spider Man jammies. Stroll past the break for an appropriately soporific video.
