With the increase in the number of obese people and the increase in work and life pressure, sleep disorders have become a problem for more and more people, among which insomnia and sleep apnea are particularly common. Survey data shows that the number of patients with sleep disorders in my country is as high as 300 million, of which 176 million suffer from sleep apnea, ranking first in the world.

Many people think that sleep disorders are far from them, and even take the harm of sleep apnea lightly. However, the "Expert Consensus on Sleep Apnea and Cardiovascular Disease" clearly points out that obstructive sleep apnea (OSA) is closely related to diseases such as hypertension, coronary heart disease, arrhythmia, heart failure, and pulmonary hypertension.

Traditional sleep diagnosis methods often require patients to stay overnight in a sleep center and be connected to many sensors for monitoring. The advent of millimeter-wave radar technology provides us with a new, contactless and more convenient option. By emitting millimeter-wave signals, the radar system can accurately capture and analyze the tiny movements of the human chest and abdomen during sleep, thereby obtaining sleep data in real time and continuously, and gaining a deep understanding of breathing patterns, sleep continuity and potential sleep disorders.
