The current sleep health field is mired in a dual dilemma: consumer-grade devices lack precision and suffer from severe artifact interference, making them unable to support clinical-level judgments; traditional medical-grade monitoring is cumbersome to wear and has extremely low compliance, making it difficult to achieve routine home-based monitoring. The sleep and heart safety of a vast population has long been in a "monitoring blind spot"—300 million people with sleep disorders and 290 million with cardiovascular diseases. Risks such as nocturnal occult arrhythmias and sleep apnea are often overlooked due to the lack of accurate, non-intrusive continuous monitoring.

Recently, Beijing Weihe Health Technology Co., Ltd., in joint application with Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, has officially obtained the invention patent certificate from the National Intellectual Property Administration for 'A Method and System for Constructing a Knowledge Graph Based on Traditional Chinese Medicine Classics' (Patent No.: ZL202510608712.X).
