In a research collaboration of the Eindhoven MedTech Innovation Center (e/MTIC), with the TU/e and the Center for Sleep Medicine Kempenhaeghe, Gabriele Papini has developed a way to monitor sleep apnea using a compact device that can be worn on the wrist. , feels comfortable and can be used for long-term home monitoring.
In clinical trials, polysomnography and polygraphic sleep apnea tests are the “gold standard” for diagnosing sleep apnea, but in either case, a person must wear sensors at night to monitor functions such as brain activity, heart rate, and muscle activity.
Therefore, these instruments are not suitable for screening and monitoring over several nights, as the sensors are uncomfortable to wear, can affect sleep and would be impossible for a person to use at home.
TU/e’s solution is a device that is worn on the wrist and looks like a smartwatch or fitness tracker, in which the skin is illuminated with green light from LEDs. Some of the light is reflected by the blood in the body and then detected by a light sensor.
For the study, 500 people, both healthy people and those with insomnia insomnia, wore the device while they slept.
