About

Youngcheol Chae is a leading innovator in sensor technology, whose work bridges the gap between flexible electronics and high-performance imaging systems. His research primarily focuses on capacitive touch sensors for wearable devices and advanced CMOS image sensors for LiDAR and range-finding applications. Chae’s most impactful contribution is the development of a graphene-based three-dimensional capacitive touch sensor for wearable electronics (2017), which has garnered 341 citations for its pioneering approach to creating conformal, stretchable input devices capable of both contact and noncontact sensing. This work has been instrumental in advancing human-machine interfaces for next-generation wearables. In the domain of optical sensing, Chae proposed a smart CMOS image sensor with high signal-to-background ratio and subpixel resolution for light-section-based range finding (2009), a key technology for obstacle recognition in autonomous vehicles and service robots. More recently, his work on SPAD flash LiDAR with a chopped analog counter (2025) demonstrates his continued push toward robust, long-range depth sensing under extreme background light conditions—achieving a 76-meter range and 120 klx tolerance. Chae’s research consistently addresses real-world challenges, from wearable interfaces to autonomous navigation, making him a pivotal figure in modern sensor engineering.
