Just a fortnight after the arrival of Amazon's Halo fitness tracker, we now learn that the company is poised to invade another segment of the wearable apparel market, one that tracks a user's sleep patterns and warns of the wearables. 'Sleep apnea. Reports suggest the new Alexa-powered device could monitor a user's sleep patterns using radar and send sleep apnea warnings. The small device was designed for the nightstand and, from its position, detects respiratory interruptions and tracks interruptions associated with sleep disturbances. It's not that the market for sleep trackers isn't crowded. Plenty of devices do the job, including the Fitbit, now owned by Google, Apple, and the new Xiaomi Mi Band 5.

A Business Insider report suggests that the project, called "Brahms," is managed by Amazon's internal team and has been in development for more than a year. The device looks like a hexagonal pad with a metal wire base, says the article, which also claims that Amazon could use its machine learning expertise to address larger problems related to sleep disorders. While Amazon has remained stoically silent on this development, taking the standard line about "it's not company policy to comment on speculation," the point is that they've been using innovative technology ever since.

When it comes to radar technology that the report says would make Amazon's sleep tracking unique, readers may recall a similar effort from Nintendo back in 2014. The idea was built around a non-wearable device capable of tracking sleep. via radio waves, but Nintendo threw it inside. two years, without even giving it a formal release. Most recently, OnePlus announced a concept phone along similar lines last month. Do you want to know the latest technological events? Follow TechRadar India on Twitter, Facebook and Instagram
