The Pro sleep monitor uses imported PVDF sensors. Based on the BCG monitoring principle, it monitors vibration signals caused by body movements, chest expansion and contraction, and heart pumping. The sensors convert these signals into electrical signals, which are then processed through amplification, filtering, and algorithmic analysis to detect heart rate, breathing, body movement, snoring, and other data. These data are then uploaded to the user’s phone and server via WiFi. Furthermore, the Pro uses a distributed flexible piezoresistive sensor with proprietary intellectual property rights to identify a person’s sleeping position.
