RESEARCH 

OHLAB (Advanced Electronic Materials Lab) focuses on the development of functional organic polymer semiconductors and advanced semiconductor devices based on these materials. Our lab develops a wide range of functional electronic systems including electronic skin (e-skin), stretchable transistors, stretchable memory, stretchable displays, stretchable sensors, and wearable energy devices, aiming to realize skin-like properties such as high stretchability, autonomous self-healing, biocompatibility, and biodegradability.

In particular, we leverage cutting-edge materials design and processing technologies such as nanocomposites of organic polymer semiconductors with elastomers, dynamic molecular bonding, nanoconfinement effects, metal-elastomer nanophase composites, and quantum-dot hybrid films to simultaneously maximize mechanical compliance and electrical performance. These materials innovations have been published in leading journals including Nature, Science, Nature Electronics, Science Advances, Nature Communications, and Advanced Materials. We have also developed various prototypes—such as skin-attachable stretchable sensors, temperature-sensing arrays, stretchable memory transistors, and full-color stretchable light-emitting devices—thereby contributing to the commercialization of next-generation wearable and bioelectronic systems.

Through numerous patents, domestic and international awards, industry-academia collaborations, and government-funded projects, our lab is actively involved in scalable manufacturing, process optimization, and commercialization-oriented technology development. We also continue to disseminate and exchange our research outcomes through active participation in national and international conferences, strengthening global competitiveness in next-generation semiconductor materials and applications. Built on a creative and challenging research environment, OHLAB is committed to pioneering innovative materials and device technologies for the emerging era of human-electronics convergence. We welcome motivated undergraduate and graduate students, as well as researchers, who are interested in advanced electronic materials and device research.
