- Unlocking New Perspectives: Angiography Synthesis from Single-view with Angle Conditions (2023.06.17)
- Unlocking New Perspectives: Angiography Synthesis from Single-view with Angle Conditions Professor Joon Sang Lee's research team from the Department of Mechanical Engineering at Yonsei University has received an outstanding paper award at the 2023 Summer Conference of the Biomedical Engineering Society for Circulation for their research titled "Unlocking New Perspectives Angiography Synthesis from Single-view with Angle Conditions." In this study, they proposed a generative artificial intelligence model that generates novel-view images from single-view image obtained from coronary angiography, which is used for the diagnosis of coronary artery disease. Through this approach, it is expected that the number of angiography scanning can be reduced, and the radiation dose exposed to patients can be decreased, thereby contributing to the improvement of the medical environment.

- Development of neural probe electrodes with low-impedance enable of three-dimensional neural signal mapping (2023.06.09)
- Development of neural probe electrodes with low-impedance enable of three-dimensional neural signal mapping Professor Jongbaeg Kim's research team in the Department of Mechanical Engineering and a research team at Korea University School of Medicine conducted a study on "Neural probe electrodes enabling to measure tiny neural signals." This study was published in the journal "Sensors and Actuators B: Chemical (Impact Factor: 8.4, top 1.58%)". Measuring complex brain nerve activity is important to overcome brain nerve diseases, such as dementia and Parkinson's disease. The probe-type electrode developed by this research team has very low impedance, so it can measure even tiny nerve signals, which were difficult with existing electrodes. Notably, this neural probe can be obtained three-dimensional nerve distribution information. The link: https://doi.org/10.1016/j.snb.2023.134124

- Polarization-sensitive intensity diffraction tomography (2023.05.18)
- Polarization-sensitive intensity diffraction tomography Professor Chulmin Joo's research team at the Department of Mechanical Engineering introduced a computational microscopy platform capable of producing tomographic birefringence images of optically anisotropic materials. Existing birefringence tomography methods mostly operate on interferometric setups, along with single-scattering models, which limits high-fidelity reconstruction of birefringence information of complex and multiple-scattering objects. The researchers developed a vectorial multiple scattering model as a method to analyze the propagation of light in multiple scattering birefringent objects, and combined it with non-interferometric microscopy setup to enable three-dimensional birefringence imaging of multiple-scattering anisotropic materials. This research was published on May 18, 2023 in the journal Light: Science & Applications (IF 20.257). The link: doi.org/10.1038/s41377-023-01151-0

- Development of human expiratory gas biomarker detection and artificial intelligence discrimination of mixed state
- Development of human expiratory gas biomarker detection and artificial intelligence discrimination of mixed state Department of Mechanical Engineering Professor Seong Chan Jun's research team and Professor Jongeun Choi's research team collaborated to conduct a study on the topic of 'Sensing the mixed state of disease biomarker gases that can be emitted through human exhaled gases and identifying artificial intelligence'. The joint research team developed an ssDNA-functionalized graphene-based sensor array that can detect mixed gases by direct adsorption method, and developed two artificial intelligence models that can discriminate the mixed state, and verified the discrimination performance. The results of this research were published as a thesis and published in the international journal 'Microsystems&Nanoengineering' (Impact Factor: 8.006). The link: doi.org/10.1038/s41378-023-00499-y

- 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.
