The Verge: Amazon is developing a new Alexa-powered device that can track and monitor for signs of sleep apnea using radar.

The palm-sized device is reportedly designed to sit on a bedside table and use millimeter-wave radar to sense your breathing, keeping an eye out for interruptions associated with the apnea sleeping disorder.

The idea of using radar to monitor sleep isn’t new, and at least one other high profile company has attempted to commercialize the technology. Way back in 2014 Nintendo announced a “non-wearable” device that could track sleep via radio waves. However, less than two years later Nintendo said it wasn’t confident the device could become a viable product, and it was never released. Last month we also saw OnePlus announce a new concept phone that used mmWave radar to monitor breathing.

Along with sleep apnea, Amazon reportedly plans to use its machine-learning and cloud technology to understand other sleeping disorders beyond sleep apnea.
