[0002] Sleep staging refers to a series of processes that divide people's sleep into different stages based on changes in electrophysiological signals. In order to accurately monitor and evaluate sleep quality, these sleep stages must be distinguished and analyzed, including light sleep, deep sleep and rapid eye movement (REM) sleep.

For example, deep sleep is beneficial to physical recovery, and REM sleep is associated with cognitive function and memory consolidation. In the prior art, traditional sleep staging usually relies on polysomnography (PSG) instruments. This equipment requires users to connect multiple sensors and monitor in a laboratory environment. The monitoring use is relatively limited, which is not conducive to sleep analysis and monitoring. Utility Model Content

The piezoelectric film module 1 is responsible for partition monitoring to ensure that the physiological signals collected by the millimeter-wave radar are not interfered by signals from other body regions.
[0023] Using two millimeter wave radar sensor modules 3 can increase the coverage of the monitoring signal and improve the accuracy of the signal and the monitoring quality.
[0024] Multiple piezoelectric film modules 1 cover different areas of the mattress 11, distinguishing and locating the user's position through different pressure changes caused by the user's weight and movement. Each piezoelectric film module 1 can accurately capture physical activity information in a specific area, and combine body motion data with signals captured by millimeter-wave radars such as heartbeat and breathing.

The individual recognition algorithm includes a machine learning component that enables it to gradually learn and improve its ability to recognize individual biological characteristics.

[0042] Furthermore, it also includes a plurality of data storage modules 8, and the plurality of data storage modules 8 exchange information with the data processing and analysis module 7 through electrical connection.
[0043] In this embodiment, a plurality of data storage modules 8 are used to store the user's sleep data for a long period of time so as to perform comparative analysis of historical data. The storage and analysis process of the sleep data uses an encryption protocol to ensure the privacy and security of the user's data.
[0044] Furthermore, it also includes a wireless module 9 and a user device 10. The wireless module 9 exchanges information with the data processing and analysis module 7 through electrical connection, and the wireless module 9 exchanges information with the user device 10 through wireless signals.
[0045] In this embodiment, the user device 10 provides a user-friendly interactive interface, and provides a universal access portal including but not limited to mobile applications, websites or other electronic communication methods for real-time display of sleep monitoring results and receiving personalized sleep improvement suggestions.
[0046] The user interactive interface further provides graphical display of historical data, trend analysis and personalized sleep analysis reports, as well as providing intervention suggestions to users when necessary.
[0047] Analysis of historical data includes long-term assessment of sleep quality, changes in sleep patterns, and early warning of potential sleep problems.
[0048] Furthermore, the surface of the millimeter-wave radar sensor module 3 is rotatably connected to a C-shaped frame 12 through a damping bearing, a bolt 13 is vertically arranged on the top of the C-shaped frame 12, the bottom end of the bolt 13 rotates and extends to the inside of the C-shaped frame 12, and is fixedly connected to a clamping plate 14, and a torsion handle 15 is fixedly connected to the top of the bolt 13.
