How does a sleep phase alarm clock work?
A sleep cycle consists of different phases that differ in terms of Brain activity, muscle tone and heart rate differentiate. Generally, there are four to six sleep cycles per night, with each cycle lasting around 90 to 110 minutes.
A typical cycle consists of:
- one sleep phase,
- several light sleep phases,
- deep sleep and
- the REM sleep
During the night’s sleep we wake up from time to time. Waking up at night is a natural process that is physiologically part of sleep. The Wachphasen can occur 10 to 30 times at night but usually only last a few seconds. A sleep phase alarm clock recognizes the different phases using sensors placed on the user’s wrist. These sensors measure various physiological parameters such as heart rate, breathing and body movement to detect the sleep cycle. When the alarm clock has determined the optimal time to wake up, it will wake the user in a light sleep phase to enable a gentle awakening. This can be done with an lsound, vibration or even a light source.

Sleep phase alarm clock: The big editorial test
set an alarm
My biorhythm I went to bed with him because of it. And what was? Inner clock out of control, sheets cruelly rumpled – and I’m exhausted in the morning. But not through the passion of the first night. But on the one hand by the “stuckness” of my bedfellow, the sleep phase alarm clock. It hung close to my wrist, pressing me. A no-go for a woman like me who belongs to the faction of the “unadorned sleepers”. And then the programming: it took hours. If only I had an IT bachelor’s degree in my pocket! In the technical Chinese, English-language accompanying booklet, there was talk of setting the “almost awake” moments, of “data review”, “to-bed feature” and of the “window function”. Sometime following midnight the fight was over: alarm clock set – I just don’t get tired anymore.
