An advanced non-wearable and contactless monitoring tracker. Based on a BCG (Ballistocardiogram) neural network model, it enables real-time detection of user’s In-Bed/Out-of-Bed Status, heart rate, respiration and body movement, while also supporting sleep stage analysis and stress index monitoring. The product incorporates PVDF nanoscale piezoelectric film technology, with sensors seamlessly embedded into the mattress comfort layer. By integrating AI neural network algorithms and large model technology, it successfully addresses the critical challenges of real-time, accurate monitoring.
