- 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.

- Research of the building profile considering the environmental flow factors of building winds in Gyeongsangnam-do province based on artificial intelligence. Professor Joonsang Lee's research team in the Department of Mechanical Engineering at Yonsei University is conducting research with local experts to solve community problems and increase social value through the Graduate Innovation Support Project called "Uggae Dong Mu" under the theme of "A Study on the Development of Artificial Intelligence-based Building Profile Considering Building Wind Flow Factors in Gyeongnam Province." The key goal of the study is to develop predictive technologies that can respond to building-wind scenarios in the Gyeongnam region. Through this study, we are expecting to develop real-time prediction technology related to building wind that can be easily used by anyone to prevent disaster risks in advance.

- An Invention of aircraft to ensure the safety of passengers (2023.01.31)
- An Invention of aircraft to ensure the safety of passengers Professor Soonho Song's research team in the Department of Mechanical Engineering has invented an airplane to ensure the safety of passengers in connection with the future mobility project. The main content of the invention relates to a flying vehicle in which a flight assistance assembly is variable to surround a boarding space in which a lighter-than-air gas is filled. Therefore, if a control module consisting of an acceleration sensor, an altitude sensor, etc., detects an abnormal condition of the aircraft, an auxiliary assembly made of elastic material can protect the boarding part.

- Development of a flexible tactile display based on liquid-to-gas phase change microactuator array (2023.01.19)
- Development of a flexible tactile display based on liquid-to-gas phase change microactuator array Professor Jongbaeg Kim’s research group in the Department of Mechanical Engineering developed a flexible tactile display that can be attached to the skin to transmit sophisticated tactile information. For sophisticated tactile transmission, this research team used a phase change actuator that can produce large output during liquid to gas phase change, and developed a device with higher spatial resolution than previous studies to enable more realistic tactile transmission to users. The study was presented at the 2023 36th IEEE MEMS Conference, the most prestigious academic conference in the MEMS field. On a basis of the excellence of the research, the presentation was selected as the Outstanding Student Poster Presentation Award Finalist, which is awarded only to 10 poster presenters among a total of 635 papers.

- Aero-manufacture of nanobulges for an in-place anticoronaviral on air filters (2023.03.05)
- Aero-manufacture of nanobulges for an in-place anticoronaviral on air filters A team of researchers lead by Professor Jungho Hwang developed an electrically operable dispenser for decorating continuous ultrafine Fe–Zn, Fe–Ag, or Fe–Cu particles (<5 nm) onto SiO2 nanobeads to form nanobulges with antiviral characteristics. The finding of this research was published the Journal of Hazardous Materials (I.F. 12.50).The resulting nanobulges were exposed to human coronaviruses (HCoV) to assess antiviral function. The nanobulges exhibited comparable antiviral activity to Zn, Ag, and Cu particles while retaining biosafety in both in vitro and in vivo models because of the significantly smaller metallic fractions. The interest in removing contagious viruses from indoor air using ventilation and filtration systems is increasing rapidly because people spend most of the day indoors. The development of an effective platform to regenerate the antiviral function of air filters during use and safe abrogation of used filters containing infectious viruses is a very challenging since an on-demand safe-by-design manufacture system is essential for in-place antiviral coatings. *This study was supported by the Technology Innovation Program (20007027, Mutually beneficial cooperative air purifying automobiles against atmospheric fine particles) funded By the Ministry of Trade, Industry & Energy (MOTIE, Korea).
