- Development of high-current density triboelectric nanogenerators based on stacked grating structures (December 1, 2024)
- Development of high-current density triboelectric nanogenerators based on stacked grating structures Professor Jongbaeg Kim’s research team from the Department of Mechanical Engineering (co-first authors of this study are Hee-jin Ko and Heejun Seong) has developed a triboelectric nanogenerator (TENG) featuring a stackable grating structure. By converting vertical displacement into lateral sliding motion, the newly developed TENG achieves a high output current density while minimizing the increase in stack height. Moreover, thanks to its robust design, the device maintained stable performance even after 45,000 consecutive cycles. Remarkably, with fewer than six mechanical deformations, it successfully powered and transmitted data from a wireless environmental sensor, demonstrating strong potential for applications in small-scale vertical vibration-based energy harvesting. These research findings were published in Nano Energy (Impact Factor: 16.8) in December 2024 The link: https://www.sciencedirect.com/science/article/pii/S2211285524010103

- The Department of Mechanical Engineering at Yonsei University successfully held the 'Yonsei Patent Concert'
- The Department of Mechanical Engineering at Yonsei University successfully held the 'Yonsei Patent Concert' On December 3, 2024, the Department of Mechanical Engineering at Yonsei University successfully held the 'Yonsei Patent Concert', a patent examination event in which undergraduate and graduate students participated together, in the 2nd Engineering Building and the Engineering College Main Auditorium. This event was hosted by the BK21 Business Group of the Department of Mechanical Engineering and was held as part of an educational program that emphasizes creative thinking and practical experience. At the event, 15 teams consisting of undergraduate students from the Department of Mechanical Engineering at Yonsei University directly demonstrated products they had developed during one semester. Approximately 60 graduate students participated as patent examiners, examining undergraduate students’ products and acting as actual evaluators. This method provided graduate students with an opportunity to indirectly experience the patent examination process and gain practical experience as examiners. As a result of the examination, a total of 4 teams were recognized for their excellent performance and received awards and prizes. ▲Grand prize: Daebakjingjo – DOS (Inseong Kim, Dongju Ko, Jaewon Kim, Chihyeon Oh, Jonghyuk Choi), ▲Excellence prize: Annual Revenue of 2 Trillion Won – Flextudy (Jungjun Kim, Bandee Kim, Jiheok Jang, Jinwook Jung, Inho Cho), ▲ Excellence prize: Combination – TAJU (Gyeongmin Park, Jonggeun Shin, Dongha Lee, Heesoo Lee), ▲ Excellence prize: RuDozer – RuDozer (Jungjin Cho, Seokwon Kim, Jihwan Yoon, Eui Yeong Jeong)

- Motion-Induced Error Reduction for Motorized Digital Fringe Projection System
- Motion-Induced Error Reduction for Motorized Digital Fringe Projection System The research team led by Professor Jae-Sang Hyun from the Department of Mechanical Engineering (with first author Sang-Hoon Jeon, in the integrated program) collaborated with the research team led by Professor Jun-Young Yoon to develop a technology that accurately reconstructs the 3D shape of fast-moving objects. By overcoming the limitations of traditional structured light reconstruction methods, which fail to accurately reconstruct moving objects due to their reliance on combining multiple patterns for 3D shape reconstruction, the team validated the effectiveness of the developed algorithm by testing it on objects moving at various speeds on a motor-driven stage. The algorithm developed through this research has been accepted for publication in the October 2024 issue of the internationally renowned journal in the field of measurement, IEEE Transactions on Instrumentation and Measurement.

- Extremely durable electrical impedance tomography–based soft and ultrathin wearable e-skin for three-dimensional tactile
- Extremely durable electrical impedance tomography–based soft and ultrathin wearable e-skin for three-dimensional tactile interfaces A collaborative research team led by Professor Ki-Joon Yoo from the Department of Electrical and Electronic Engineering and Professor Jongbaek Kim from the Department of Mechanical Engineering has developed the world's first ultra-thin, highly durable electronic skin. The team fabricated a 50 μm-thick ultra-thin electronic skin by integrating multi-walled carbon nanotubes (MWCNTs) with stretchable silicone and utilized electrical impedance tomography (EIT) to monitor internal conductivity changes in real time. This innovation achieved high durability and stable operation, successfully demonstrating its performance in various human-machine interfaces (HMI), such as drone control. This research overcomes the limitations of complex multi-channel array structures by integrating computational engineering techniques to create high-performance electronic skin resembling human skin. It represents a significant contribution to the advancement of next-generation HMI technologies. The findings were published on September 20, 2024, in Science Advances (Impact Factor: 11.7), a leading journal in interdisciplinary research, and were featured in various news media.
