The other main group of nearable sleep trackers use a non-contact method to collect physiological sleep data entirely by means of radio frequencies. You can then access this data via your computer or smart phone. When you lie down, the sensor picks up your movement, breathing and heart-rate data and relays this back wirelessly to a cloud sever for analysis and processing. Both devices consists of a sensor strip which you place under your mattress or mattress topper. The Withings Sleep Analyzer and Emfit QS are examples of a nearable technology called ballistocardiography. As part of the ‘internet of things’, nearables encompass a range of objects and devices that contain sensors which can measure and collect data about yourself, and send this on to a smartphone, tablet, computer or cloud server for further analysis and processing. Nearable technology is not new, nor is it exclusive to sleep tracking devices. But essentially you could say that nearables allow you to achieve the same things as wearables without being physically attached to the consumer. That’s a simplification, but as with all new jargonistic terms, there’s usually some flexibility with definitions. You get it right? It’s like a wearable, but instead of something your wear on your body, the device merely has to be near your body. enter the new, exciting world of nearables. One that you never even have to touch again once you’ve set it up? What are nearables? One that you only had to use when you’re actually sleeping? One that you never have to worry about how much battery life you’ve got. what if there was a different type of sleep tracker.
