Real-Time Position Detecting of Large-Area CNT-based Tactile Sensors based on Artificial Intelligence
인공지능을 기반으로 한 대면적 CNT 기반 촉각 센서의 실시간 위치 탐색 연구
Min-Young Cho, Seong Hoon Kim, Ji Sik Kim
조민영, 김성훈, 김지식
Korean J. Met. Mater. 2022;60(10):793-799.   Published online 2022 Sep 29
DOI: https://doi.org/10.3365/KJMM.2022.60.10.793

For medical device and artificial skin applications, etc., large-area tactile sensors have attracted strong interest as a key technology. However, only complex and expensive manufacturing methods such as fine pattern alignment technology have been considered. To replace the existing smart sensor, which has to go through a complicated process, a..... More

Optimization of Two-Stage Hybrid Forming Process via Quantitative Assessment of Mechanical Properties in AA5052
Sang Soo Lee, Seon Du Choi, Ho Geun Shin, Suman Timilsina, Seong Min Jang, Young Seon Lee, YongNam Kwon, Ji Sik Kim
Korean J. Met. Mater. 2022;60(5):391-399.   Published online 2022 Apr 22
DOI: https://doi.org/10.3365/KJMM.2022.60.5.391

Superplastic forming (SPF) is a promising approach used for manufacturing parts with complex geometries, especially in the automotive, aerospace, and marine industries. However, the wider use of this method is limited by issues of low forming rate, high-temperature requirement, non-uniform thickness distribution, and expensive base materials. The two-stage hybrid forming..... More

Ultraviolet Light-Responsive Photorheological Fluid for Sensors and Actuators Realized by Phosphorescence Effects and LSTM RNN
Min Young Cho, Suman Timilsina, Jong Wook Roh, Walter Commerell, Ho Geun Shin, Yong-Nam Kwon, Ji Sik Kim
Korean J. Met. Mater. 2021;59(5):346-353.   Published online 2021 Apr 6
DOI: https://doi.org/10.3365/KJMM.2021.59.5.346

A photo-rheological fluid (PRF) is a smart fluid which exhibits different viscosity under UV irradiation. A PRF is comprehensively presented in this work, with particular focus on its responses under UV off/on conditions. The isomeric conversion from SP to MC and vice versa under UV off and on, respectively, showed..... More
