Director Ahn at Startup KAIST Donates 100 Million KRW for Aspiring Entrepreneurs
< Director Steve Ahn (Right) > Steve Ahn, the Director of Startup KAIST, donated one hundred million KRW of development fund to his alma mater KAIST to increase entrepreneurship opportunities and nourish start-up culture on campus. Professor Ahn founded Leadis Technology Inc. in 2000, a fabless semiconductor company based in Silicon Valley that develops mobile phone sub-display applications. Leadis Technology Inc. made its stock market debut on the NASDAQ in 2004. “KAIST produces many start-ups, however, entrepreneurial culture has yet to become a growth engine of KAIST, compared to education and research. Through invigorating entrepreneurial spirit and revitalizing start-up activities, KAIST should reclaim its leadership role in creating decent jobs and fuelling economic growth and competitiveness at home and abroad,” he said during the donation ceremony last month. He added, “I am forever grateful to my alma mater KAIST for having provided me with a quality education. It was a valuable asset that helped me gain an opportunity to nurture the up-and-coming, next-generation scholars as a professor at KAIST. I decided to make this donation hoping that KAIST students will be given more entrepreneurship opportunities, and a healthy start-up ecosystem will be accelerated beyond KAIST.” Director Ahn earned his bachelor’s degree in metallurgy from Seoul National University, followed by a master’s degree in materials engineering from KAIST. He received another master's degree in electrical engineering, and was granted a doctorate in materials engineering from Stanford University. He has been mentoring start-up activities at Startup KAIST since 2014, and serving as the principal professor at K-School since 2016. From these activities, he was recognized for his academic achievements and committed leadership, which led him to be appointed as the Director of Startup KAIST in March 2019. (END)

A System Controlling Road Active Noise to Hit the Road
The research team led by Professor Youngjin Park of the Department of Mechanical Engineering has developed a road noise active noise control (RANC) system to be commercialized in partnership with Hyundai Motor Group. On December 11, Hyundai Motor Group announced the successful development of the RANC system, which significantly reduces the road noise flowing into cars. The carmaker has completed the domestic and American patent applications for the location of sensors and the signal selection method, the core technology of RANC. RANC is a technology for reducing road noise during driving. This system consists of an acceleration sensor, digital signal processor (the control computer to analyze sound signals), microphone, amplifier, and audio system. To make the system as simple as possible, the audio system utilizes the original audio system embedded in the car instead of a separate system. The acceleration sensor first calculates the vibration from the road into the car. The location of the sensor is important for accurately identifying the vibration path. The research team was able to find the optimal sensor location through a number of tests. The System Dynamics and Applied Control Laboratory of Professor Park researched ways to significantly reduce road noise with Hyundai Motor Group for four years from 1993 as a G7 national project and published the results in international journals. In 2002, the researchers published an article titled “Noise Quietens Driving” in Nature, where they announced the first success in reducing road noise in actual cars. The achievement did not lead to commercialization, however, due to the lack of auxiliary technologies at the time, digital amplifiers and DSP for cars for example, and pricing issues. Since 2013, Professor Park’s research team has participated in one technology transfer and eight university-industry projects. Based on these efforts, the team was able to successfully develop the RANC system with domestic technology in partnership with Hyundai’s NVH Research Lab (Research Fellow, Dr. Gangdeok Lee; Ph.D. in aviation engineering, 1996), Optomech (Founder, Professor Gyeongsu Kim; Ph.D. in mechanical engineering, 1999), ARE (CEO Hyeonseok Kim; Ph.D. in mechanical engineering, 1998), WeAcom, and BurnYoung. Professor Park’s team led the project by performing theory-based research during the commercialization stage in collaboration with Hyundai Motor Group. For the commercialization of the RANC system, Hyundai Motor Group is planning to collaborate with the global car audio company Harman to increase the degree of completion and apply the RANC system to the GV 80, the first SUV model of the Genesis brand. “I am very delighted as an engineer to see the research I worked on from my early days at KAIST be commercialized after 20 years,” noted Professor Park. “I am thrilled to make a contribution to such commercialization with my students in my lab.”

New Liquid Metal Wearable Pressure Sensor Created for Health Monitoring Applications
Soft pressure sensors have received significant research attention in a variety of fields, including soft robotics, electronic skin, and wearable electronics. Wearable soft pressure sensors have great potential for the real-time health monitoring and for the early diagnosis of diseases. A KAIST research team led by Professor Inkyu Park from the Department of Mechanical Engineering developed a highly sensitive wearable pressure sensor for health monitoring applications. This work was reported in Advanced Healthcare Materials on November 21 as a front cover article. This technology is capable of sensitive, precise, and continuous measurement of physiological and physical signals and shows great potential for health monitoring applications and the early diagnosis of diseases. A soft pressure sensor is required to have high compliance, high sensitivity, low cost, long-term performance stability, and environmental stability in order to be employed for continuous health monitoring. Conventional solid-state soft pressure sensors using functional materials including carbon nanotubes and graphene have showed great sensing performance. However, these sensors suffer from limited stretchability, signal drifting, and long-term instability due to the distance between the stretchable substrate and the functional materials. To overcome these issues, liquid-state electronics using liquid metal have been introduced for various wearable applications. Of these materials, Galinstan, a eutectic metal alloy of gallium, indium, and tin, has great mechanical and electrical properties that can be employed in wearable applications. But today’s liquid metal-based pressure sensors have low-pressure sensitivity, limiting their applicability for health monitoring devices. The research team developed a 3D-printed rigid microbump array-integrated, liquid metal-based soft pressure sensor. With the help of 3D printing, the integration of a rigid microbump array and the master mold for a liquid metal microchannel could be achieved simultaneously, reducing the complexity of the manufacturing process. Through the integration of the rigid microbump and the microchannel, the new pressure sensor has an extremely low detection limit and enhanced pressure sensitivity compared to previously reported liquid metal-based pressure sensors. The proposed sensor also has a negligible signal drift over 10,000 cycles of pressure, bending, and stretching and exhibited excellent stability when subjected to various environmental conditions. These performance outcomes make it an excellent sensor for various health monitoring devices. First, the research team demonstrated a wearable wristband device that can continuously monitor one’s pulse during exercise and be employed in a noninvasive cuffless BP monitoring system based on PTT calculations. Then, they introduced a wireless wearable heel pressure monitoring system that integrates three 3D-BLiPS with a wireless communication module. Professor Park said, “It was possible to measure health indicators including pulse and blood pressure continuously as well as pressure of body parts using our proposed soft pressure sensor. We expect it to be used in health care applications, such as the prevention and the monitoring of the pressure-driven diseases such as pressure ulcers in the near future. There will be more opportunities for future research including a whole-body pressure monitoring system related to other physical parameters.” This work was supported by a National Research Foundation of Korea (NRF) grant funded by the Ministry of Science and ICT. < Figure 1.

Korea Policy Center for the Fourth Industrial Revolution Opens
The World Economic Forum’s Center for the Fourth Industrial Revolution opened its Korean affiliate center at KAIST on December 10. The Korea Policy Center for the 4th Industrial Revolution (KPC4IR) will develop policy norms and frameworks for accelerating the benefits of emerging technologies. Many dignitaries including KAIST President Sung-Chul Shin, National Assemblyman Sang-Min Lee, Daejeon City Mayor Her Tae-Jeong, and Managing Director of the WEF Center for the Fourth Industrial Revolution Murat Sonmez attended the opening ceremony. The center will play a vital role in helping to shape the development of national Fourth Industrial Revolution strategies and public-private initiatives. The Center will actively engage with the government on policy design and piloting activities. The Center is the result of KAIST’s close partnership with the WEF and its Center for the Fourth Industrial Revolution in San Francisco. KAIST signed an MOU with the WEF in 2017 for this collaboration. Dr. Klaus Schwab expressed his high hopes many times regarding Korea’s potential in responding to the Fourth Industrial Revolution. In addition, he said that KAIST and the City of Daejeon would play a significant role in helping the Fourth Industrial Revolution move forward. During a meeting with President Moon Jae-In last June, Dr. Schwab expressed his strong desire to collaborate with Korea, and the Korean government designated KAIST as an affiliate center of the WEF. The KPC4IR had already begun conducting policy research in the areas of block chain and precision medicine even before making a partnership with the WEF. The director of the Center, Distinguished Professor Sang Yup Lee, said, “We have focused on the development of technology but rarely talk about governance. Technology should come with policy. We will conduct policy development on how to ensure inclusive growth capitalizing on emerging technologies. We will also make policy guidelines for technological applications after considering all the ethical perspectives. President Shin also said in his opening remarks, “Korea has been a fast follower over the past decades in making economic development and innovations. I believe that the Fourth Industrial Revolution gives us the best opportunity to play the role of ‘first mover.’ I look forward to the KPC4IR serving as a ‘Think and Do’ tank, not limiting itself to the role of ‘think tank.’ We will continue to work closely with the WEF in the fields of AI, blockchain, and precision medicine.
