Kim is also collaborating with a team of South Korean researchers from the department of Robotics Engineering at Daegu Gyeongbuk Institute of Science and Technology (DGIST), and PROTEM Co Inc, a technology-based company, for the development of printable conductive ink materials.

In this second project, researchers have developed a new breakthrough in the embossing process technology, one that can freely imprint fine circuit patterns on flexible polymer substrate, a necessary component of electronic products.

Embossing technology is applied for the mass imprinting of precise patterns at a low unit cost. However, Kim says it can only imprint circuit patterns that are imprinted beforehand on the pattern stamp, and the entire, costly stamp must be changed to put in different patterns.

The team succeeded in developing a precise location control system that can imprint patterns directly, resulting in a new process technology. This will have widespread implications for use in semiconductor processes, wearable devices and the display industry.
