Bioinstrumentation System for Digital Health Platform: Sleep Health Monitoring Technologies Using Watch-Type Wearable – Hyunjun Jung

Digital health leverages information and communication technologies to transform healthcare, enabling diverse solutions for continuous health management. Among these, wearable-based digital health plays a key role by collecting, monitoring, and analyzing physiological data over extended periods. In this lecture, I will introduce the sleep-related features of Samsung’s Galaxy Watch series, focusing on the biosignals that can be acquired from the wrist and how they are processed. I will also share practical insights from the research and validation processes that enabled these features. Through this, I aim to show how your specialized, in-depth research can be translated into real-world, impactful digital health applications, and what key factors must be considered in that process.

Biography

Hyunjun Jung is a Principle Engineer at Samsung Electronics’ MX Division (formerly Mobile Division), where he has been leading the research and development of various commercial solutions for the Galaxy Watch since April 2018. He played a pivotal role in the development of Samsung’s first wearable ECG device, the Galaxy Watch Active 2, and contributed to the FDA 510(k) approval for its AFib(Atrial Fibrillation) detection feature. Additionally, he spearheaded the development of the world’s first FDA-approved (De Novo) sleep apnea detection function. He has also independently developed and validated solutions for oxygen saturation, sleep score, respiration rate during sleep, and heart rate, aiming to deliver more accurate health monitoring features to users.
