We are leading medical technology innovation through clinical research and AI research based on the world's largest biosignal dataset and biosignal utilization platform.

VitalLab, under the direction of Professor Chul-Woo Jung and Professor Hyung-Chul Lee, conducts research on optimizing health care by collecting perioperative biosignal data and analyzing it with AI models designed by our clinicians and engineers. For example, using our perioperative data collections and AI technologies such as modeling, pattern recognition, and machine learning, our lab researchers generated a predictive model for the bispectral index during target-controlled infusion of propofol and remifentanil.

With VitalRecorder, built and developed by Prof. Lee to record and analyze vital signs, we have built VitalDB: the world's largest biosignal dataset and biosignal utilization platform. Please click "Learn more" below for more detailed information about VitalRecorder and VitalDB.
