Professor Sooseok Choi's research team at POSTECH developed a precise visualization and evaluation method for strain in stretchable structures. Their research was published in Advanced Science On-Line and selected as the cover paper.

Professor Sooseok Choi’s research team at POSTECH, consisting of Ph.D. students Sanghyun Han (first author), Joonhyuk Shin, Hakjun Yang, Post-Doc Seungmin Nam, and Ph.D. student Jiyoon Park (advisor: Prof. Sooseok Choi), developed the first method to accurately measure the fine structural characteristics that occur throughout the stretching process of the serpentine structure, a key technology in stretchable electronics, and visualize these characteristics through color representation. Their research was selected as the Inside Back Cover cover study and published online in the interdisciplinary journal Advanced Science (IF 14.3).
