BST relies on a 3-channel movement detection method, originally designed for the Static Charge Sensitive Bed. One of the recent commercially available home sleep monitoring devices is the Beddit Sleep Tracker (BST), a thin strip sensor placed under the mattress or mattress topper. The preliminary research findings have shown promise for this multidata approach, 14 but further studies are still required. 7 One such novel device is the ŌURA ring, which in addition to actigraph data, collects heartbeat variation, heart rate and other variables from the finger to evaluate sleep parameters. 2, 4, 13 Recently, multidata approaches have gained ground and actigraphy devices have been used aside other data sources, such as the peripheral arterial blood flow tone. 12 Actigraphs have problems in detecting wakefulness, and as a result, overestimate both total sleep time and sleep efficiency. 2, 4, 11, 12 Actigraphy studies have provided mixed results, yet are currently used, for example, as an adjunct measure in sleep apnea monitoring. The latter, movement measurement devices, include increasingly popular actigraphs, which are light wearable devices, usually connected to wrist, ankle or hip that provide information via an accelometer. Of the former, the most promising EEG methods (Zeo headband with 74 % PSG agreement 3 and the Nightcap with 93 % PSG agreement 10) have unfortunately been discontinued and are no longer commercially available. 1, 5, 7 – 9 Most of the sleep measures rely on either electroencephalography (EEG) or movement (cardiac, respiratory or body movements) data. Thus far, however, only a few affordable home sleep monitoring devices have been validated against PSG. The current gold standard, polysomnography (PSG), is labor-intensive and costly in terms of time and resources, and as such often unfeasible for clinical or research settings. 1 – 5 Additionally, there is an urgent need in both clinical and research settings for a cost-effective, portable and reliable measuring device for studying sleep 6 in home settings. Hopefully whatever Apple has planned will work at least as well, and won’t require users to wear special gear to bed.Recent rise of interest in consumer health monitoring has spurred the development of mobile devices designed to measure objective sleep parameters. I especially liked that I didn’t have to wear any devices, like a wrist sensor, while I slept. I learned a lot about my own sleep issues from my Beddit and was able to work on strategies to help counter my insomnia. Seeing the Beddit sleep monitor discontinued is especially sad for me. Regardless of what Apple has planned, the Beddit 3 Sleep Monitor looks to have reached the end of its life. That could be as apps for the iPhone and Apple Watch, or as some sort of accessory or new product. If more were being manufactured, Apple’s site would have an estimated shipping date instead.īuying the company is a hint that Apple plans to offer some sort of sleep tracking through its own products. TMO readers noted it’s been listed as “sold out” for more than a week, which is a pretty good indication Apple is simply killing off the product. It included a companion iPhone app where your sleep activity was logged. The Beddit sleep tracker included a special sensor strip for your mattress that tracked your movement and respiration while you slept. ![]()
