- 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.

- Honored with Two Outstanding Presentation Awards at the International Conference on Precision Engineering and Sustainabl
- Honored with Two Outstanding Presentation Awards at the International Conference on Precision Engineering and Sustainable Manufacturing 2024 (PRESM 2024) The research team, led by Professor Jun Young Yoon from the Department of Mechanical Engineering (Hyo Geon Lee, Ph.D. candidate, and Chang Hwan Kim, M.S. candidate) has been recognized for their outstanding achievements in two research topics at the International Conference on Precision Engineering and Sustainable Manufacturing held in July 2024. Hyo Geon Lee developed a high-speed, high-accuracy motor analysis technique based on the magnetic permeability matrix for a magnetic flux-switching motor using transverse permanent magnets. This method achieved higher analytical precision compared to existing magnetic circuit-based methods and demonstrated its potential as a promising method in the early stages of design optimization. Chang Hwan Kim presented a control algorithm for maintaining the dynamic performance of a 6-DOF magnetic levitation system, considering changes in payload. As the payload changes, the dynamic characteristics of the system also change, resulting in the degradation of control performance. To address this, he designed a mass-compensator and validated its efficacy by comparing the control performance under varying payloads. The two studies were selected for the 'Outstanding Presentation Award,' given to only 22 out of 305 presentations. The link: https://2024.presm.org/
