Core Viewpoint - A new wearable all-in-one obstructive sleep apnea management system has been developed, integrating flexible piezoelectric monitoring and soft magnetoelastic stimulation, addressing the limitations of traditional polysomnography (PSG) in cardiovascular parameter monitoring [4][11]. Group 1: Research Development - The research was a collaboration between Southwest Jiaotong University, City University of Hong Kong, and West China Hospital of Sichuan University [2]. - The developed system features a customized piezoelectric composite sensor for continuous physiological signal monitoring and a soft magnetoelastic actuator for non-invasive mechanical stimulation [7][11]. - The system utilizes a machine learning algorithm to achieve a 92.7% accuracy rate in real-time detection of sleep apnea events [8]. Group 2: Clinical Validation - Rigorous laboratory and clinical studies demonstrated that the developed apnea management system (AMS) is comparable to the clinical gold standard, PSG, in identifying apnea events [9]. - Parallel comparison signals from AMS and PSG confirmed the effectiveness of feedback stimulation [11]. Group 3: System Features and Benefits - The AMS integrates continuous physiological monitoring and non-invasive mechanical stimulation, providing a closed-loop system for sleep apnea management [11]. - This system not only addresses the limitations of traditional PSG in tracking cardiovascular responses but also offers a scalable and user-friendly platform for personalized sleep health care at home [11][12].
