Dr. Liu’s research leverages artificial intelligence and microelectronics to innovate sleep medicine and cardiac dynamics. His work focuses on using non-contact bio-motion sensors to monitor vital signs during sleep, enabling advanced analysis of arrhythmias and comprehensive sleep assessments, particularly in the detection and analysis of cardiac anomalies during sleep, such as irregular heartbeats and arrhythmias.

Dr. Liu has developed innovative AI-driven systems that capture heartbeats, respiratory signals, and body movements in a non-contact and non-wearable method. This technology offers precise, long-term health monitoring and diagnostic capabilities. His research includes not only the detection and analysis of sleep-related cardiac anomalies but also the improvement of sleep quality and health through targeted interventions throughout the sleep process.
