Sleep tracking: Go2Sleep, the wearable sleep tracker that can detect sleep apnea

Sleepon is set to launch Go2Sleep, a silicone ring designed to detect sleep apnea more affordably.



As reported by the website Megagadget, the startup Sleepon recently launched a crowdfunding campaign for its first product, which goes by the name of Go2Sleep. According to its designers, it is the smallest sleep apnea detection ring in the world.

Sleep apnea is a condition in which sufferers’ breathing is interrupted during sleep, which can cause irritability, headaches and daytime sleepiness. If untreated, sleep apnea can also lead to high blood pressure, irregular heartbeat, and strokes. It currently affects around 25 million Americans, though many more people are likely to be undiagnosed. In the face of this major public health issue many companies, among them Apple and FitBit, have embarked on projects looking at ways of improving sleep apnea diagnosis.


Fitted with sensors


Sleepon’s Go2Sleep takes the form of a ring made of waterproof medical silicone. Weighing no more than six grams, the user slips it on a finger before going to bed. On waking up, they take it off and place it on the charging dock. Available in three sizes, this comfortable device has a battery life of about three days.

Though small in size, Go2Sleep is fitted with a number of sensors, including a 3-axis accelerometer and a pulse oximeter to record the user’s movement, heart rate, perfusion index, and blood oxygenation level. Such measurements are all essential in trying to identify sleep apnea, as blood oxygenation levels drop and heart rate increases when a person temporarily stops breathing in their sleep. 


Early detection 


While the user sleeps, the Bluetooth-enabled Go2Sleep continuously captures and stores this data, which is then interpreted by an artificial intelligence algorithm to provide the user with daily and weekly sleep reports through the free SleepON App or email.

As the Sleepon device has yet to obtain Food and Drug Administration (FDA) approval, users must still consult with their healthcare providers to reach a definitive conclusion. Furthermore, given that Go2Sleep cannot directly measure airflow or respiratory effort, it cannot differentiate between obstructive and central sleep apnea – the two main types of sleep apnea – unlike the devices used by sleep laboratories in conducting full-scale sleep studies (polysomnographies).

Though not the definitive solution, Go2Sleep provides competition for WatchPat – the leading system on the market – and at a more competitive price of $99. It should be available by May 2018.
