A Sensor That Stretches Like Skin and Even Generates Power from Seawater 鈥� Development of a 鈥榁ersatile Hydrogel鈥�-Professor Kim Yong-hyun鈥檚 Team at 狠狠撸 Presents a Next-Generation Material for Wearable Sensors A next generation 鈥渁ll-in-one hydrogel鈥�, which is highly sensitive to electrical signals, stretches like human skin, and even generates electricity when immersed in seawater, has been developed by a Korean research team. A research team led by Professor Kim Yong-hyun (Department of Display and Semiconductor Engineering) at 狠狠撸 has developed a high-performance hydrogel by combining xanthan gum, a natural polymer, with polyvinyl alcohol (PVA), a biocompatible polymer. This new material maximizes both mechanical strength and electrical conductivity. The key achievement of this research lies in overcoming the long-standing trade-off between mechanical strength and ionic conductivity in conventional hydrogel studies. The team accomplished this by introducing a proprietary 鈥渄ual crosslinking and ion treatment鈥� process. Specifically, they applied dual crosslinking鈥昦 combination of physical and chemical bonds鈥晅o reinforce the hydrogel鈥檚 internal framework. This was followed by an ion treatment process that not only enhanced the material鈥檚 conductivity but also further stabilized its structure. As a result, the developed hydrogel is over 20 times stronger than conventional types and can stretch more than four times its original length (with an elongation of 410.2%). It also achieved exceptionally high ionic conductivity (5.23 S/m). Furthermore, it demonstrated minimal signal distortion (hysteresis) during repeated movements, ensuring excellent stability and reliability as a sensor material. Building on these properties, the research team successfully applied the hydrogel as a wearable sensor by attaching it to the skin to monitor various human movements. The sensor accurately detected both large joint motions鈥晄uch as finger and knee movements鈥昦nd subtle physiological signals, including pulse, breathing, and swallowing. When the collected data was analyzed using artificial intelligence (AI), the sensor achieved a high classification accuracy of 84.9%, proving its potential as a human-machine interface (HMI). In addition, the team demonstrated that hydrogel could serve as a power generator for sustainable energy. Using the principle of osmotic power, electricity was generated as ions moved between the hydrogel and seawater due to the difference in salt concentration. The team successfully connected multiple hydrogel units in series to light an LED lamp, confirming the material鈥檚 potential as an eco-friendly energy source. The results of this study were published in the internationally renowned journal

The system, titled 鈥渞edox-responsive crosslinked maltopheptaose-based micelles,鈥� was developed by Ph.D. candidate Byeong Kook Kim (Department of Industry 4.0 Convergence Bionics Engineering) as the first author, with Professor Kwon Taek Lim (Professor Emeritus) and Professor Sang-Hyug Park (Major of Biomedical Engineering, Division of Smart Healthcare) as corresponding authors. The system was developed to overcome the limitations of low anticancer efficacy caused by the nonspecific delivery of doxorubicin, a potent anticancer drug widely used in the treatment of various cancers but known to cause several side effects. The system developed by the 狠狠撸 research team is composed of an A2B-type miktoarm block copolymer based on maltopentaose, a biocompatible oligosaccharide. It incorporates disulfide or diselenide crosslinking within the micelle core, enabling selective drug release only upon reaching cancer cells, while minimizing effects on healthy tissues. Experimental results showed that the system exhibited high drug-loading efficiency, demonstrating biocompatibility with normal cells and strong anticancer effects against cancer cells. Professor Sang-Hyug Park stated, 鈥淭his study is significant in that it presents a novel method to overcome the early leakage of drugs into the bloodstream鈥昦 major issue in conventional drug delivery systems, which often leads to various side effects. The system holds promise for applications in precision anticancer drug delivery and reduced-side-effect nanomedicine platforms, garnering considerable interest from both academia and industry.鈥� The findings of this study were recently published in the prestigious international journal

狠狠撸 and NIER Research Team Unveils First Findings on Diurnal Variation of NO鈧� Concentrations in Asia- Collaborative Study with Researchers from the U.S., Belgium, and Germany Published in an International JournalA research team led by Professor Lee Han-lim (Department of Satellite Information Convergence Engineering) at 狠狠撸, in collaboration with the National Institute of Environmental Research (NIER), has become the first to identify the diurnal variation characteristics of nitrogen dioxide (NO鈧�) concentrations in major Asian cities, including Seoul and Beijing. The joint study by Professor Lee Han-lim鈥檚 team and Dr. Hong Hyun-ki of NIER was published on May 19 in Communications Earth & Environment, a sister journal of Nature, under the title 鈥楾ropospheric nitrogen dioxide levels vary diurnally in Asian cities.鈥� Professor Lee Han-lim collaborated with researchers from world-renowned institutions, including Dr. Park Jun-sung (first author) of the Harvard-Smithsonian Center for Astrophysics, as well as scientists from NASA, the Belgian Institute for Space Aeronomy (BIRA-IASB), and the Max Planck Institute for Chemistry (MPIC) in Germany. The research team utilized observational data from the Geostationary Environment Monitoring Spectrometer (GEMS), the world鈥檚 first geostationary environmental satellite developed and launched by the National Institute of Environmental Research. Using this data, they precisely analyzed the diurnal variations in NO鈧� concentrations across major cities in Asia. Thanks to the satellite鈥檚 ability to observe the same region multiple times a day, the researchers were able to reflect hourly changes in their models. As a result, they successfully produced the world鈥檚 most precise top-down simulation estimates of NO鈧� emissions. The study revealed notable regional differences in the diurnal variation of NO鈧� concentrations. On average, Seoul experienced low NO鈧� levels in the early morning, which peaked around 11 a.m., declined, and then rose again at approximately 3 p.m. In Beijing, levels peaked at 10 a.m. and dropped to their lowest around 4 p.m., while in Shanghai and surrounding areas, concentrations reached a high at 8 a.m. and a low at 1 p.m. This research is recognized for its contribution in enabling hour-by-hour estimation of nitrogen oxide emissions by providing tropospheric NO鈧� concentration data at high temporal resolution. It is also expected to improve the accuracy of existing bottom-up emission inventories, which are commonly used for calculating greenhouse gas emissions.
