No.161 / Dec 12, 2022
Our university has succeeded in technology transfer by jointly developing a “wide-range hydrogen concentration detection electric sensor”. This is a follow-up result after securing more than 2.5 billion won in technology transfer fees with related technology in July 2021. Through this technology transfer, the school secured 1.2 billion won in technology transfer fees and royalties in sales. This technology was developed by Professor Seo Hyung-tak (the Department of Materials Science and Engineering and graduate school of the Department of Energy Systems) and Park Jang-ho (the dean of the engineering college). It is a technology that solves the shortcomings of hydrogen sensors with a palladium (Pd) - nickel (Ni) layer structure and is a highly reliable semiconductor process technology with a detection concentration of 1ppm-100% in the absence of localization technology. It means that it is 100% detectable to 0.0001% of the amount of hydrogen leakage. Based on this technology, hydrogen leakage can be detected, and hydrogen concentration can be measured with high accuracy in real-time in hydroelectric cars. It is the world’s first hydrogen sensor with measurable wide-range concentration as a single element.
Professor Seo Hyung-tak previously transferred the “discoloration sensor technology for hydrogen leakage detection” to Daehyun ST Co., Ltd. in July 2021. This was valued at 2.5 billion won, the largest achievement in the non-bio sector since Ajou University opened. Developed by Professor Seo’s research team, this technology is a high-performance and high-precision sensor that can accurately measure hydrogen concentration and is a necessary technology to secure the safety of hydrogen utilization. This technology is composed of a solution synthesis method and semiconductor deposition method, so the expansion of various hydrogen application fields is possible to construct sensor processes suitable for use.
Our university has been performing well in the technology commercialization sector, ranking 4th among universities nationwide with a technology transfer profit of 5.21 billion won in 2021. Ajou University is expected to continue to develop technology and move forward with non-stop technology transfer, long may it continue to do so.
