- Integration of Mechanically Resilient, Alumina-Reinforced Carbon Nanotube Arrays for In-Plane Shock Absorption in Micromechanical Devices The research team led by Professor Jongbaeg Kim, including co-first authors Research Professor Eunhwan Jo and master's researcher Hojoon Lee, has conducted a study on ceramic-reinforced carbon nanotube-based shock absorbers. The study focuses on the usage in the field of micro/nano electromechanical systems (MEMS/NEMS) and has been approved for publication in an international journal 'Microsystems & Nanoengineering' which has Impact Factor of 8.006, placing it in the top 6.25% in the field of Instrument & Instrumentation. The researchers integrated vertically aligned nanotube bundles into MEMS to enhance the shock capability of microstructures against impacts. This advancement is particularly significant as it addresses the vulnerability of subminiature devices to impact. This study is collaborated with Harvard Medical School in the United States to strengthen the study's potential impact. It's worth mentioning that this study received support from the 'Midcareer Research Grant' funded by the Ministry of Science and ICT, leaded by Prof. Jongbaeg Kim as a project investigator.

- Awarded the grand prize in the 2023 Autonomous Driving Robot Race Competition (2023.04.01)
- Awarded the grand prize in the 2023 Autonomous Driving Robot Race Competition Under the guidance of Professor Jongeun Choi, Yonsei University's Mech in AI team won the grand prize at the 1st competition of the 2023 Autonomous Driving Robot Race held at the C-track of Chungbuk National University's Ochang Campus. This is the only competition in Korea that the autonomous vehicles start simultaneously, and requires using various autonomous driving strategies such as lane changing, overtaking, and vehicle-to-vehicle contact avoidance. This research team developed autonomous driving technologies such as multimodal sensor fusion, obstacle avoidance algorithms, and condition prediction-based control systems, and installed them in vehicles to complete the race.

- An invention of the aeroplane power system using two types of power modules (2023.02.23)
- An invention of the aeroplane power system using two types of power modules Professor Soonho Song's research team in the Department of Mechanical Engineering invented an aircraft power system using two types of power modules. The main power module of the present invention is an internal combustion engine, and the additional power assembly is configured in a form in which an auxiliary working fluid in a low-temperature liquefied material state is stored. If a problem occurs in a power source or a higher output than the maximum output of a single power source is required, two types of power modules can be solved.

- A Stretchable Strain-insensitive Tactile Sensor Array without Crosstalk Effect (2023.02.20)
- A Stretchable Strain-insensitive Tactile Sensor Array without Crosstalk Effect (2023.02.20) Kyubin Bae, a doctoral student from Professor Jongbaeg Kim in the Department of Mechanical Engineering, has been awarded the Silver Prize in the Mechanical Engineering Division of the 29th Samsung Humantech Paper Award. Established in 1994 to recognize outstanding young scientists, this competition is hosted by Samsung Electronics. The research team introduced an original technology called "tactile sensor that eliminates interference between tension and adjacent cells." The fabricated sensor has been recognized for its superior performances such as high sensitivity and wide sensing range. The developed sensor has been shown to selectively detect pressure information in an environment where large deformation occurs, such as human joints, indicating its potential use in the health monitoring field, a next-generation industry.
