After graduating from Huazhong University of Science and Technology with his Master Degree in High Voltage Engineering in 1985, he joined Wuhan High Voltage Research Institute of State Grid. He received several First-class, Second-class and Special Award from State Grid, Chinese Electric Power, and the government for his achievement in EHV and UHV transmission, high voltage engineering, and transmission line inspection and maintenance. Kai Liu is currently a Professor and Doctoral Supervisor at the School of Polymer Science and Engineering, Qingdao University of Science and Technology. He obtained his Ph.D. from the University of Chinese Academy of Sciences (2018-2022), followed by a post as an Assistant Researcher at Peking University’s School of Materials Science and Engineering (2022-2024). He assumed his current professorship at Qingdao University of Science and Technology in 2024. His research focuses on functionalized elastomers, flexible semiconductor materials, flexible sensors, thermoelectric conversion, and photodetection. He has authored/co-authored more than 30 publications as first or corresponding author in prestigious journals including Nature, Nature Communications, Advanced Materials, and Journal of the American Chemical Society. Additionally, he holds the position of Youth Editorial Board Member for Wearable Electronics and Chinese Chemical Letters.
