Structural vibration-based classification and prediction of delamination in smart composite laminates using deep learning neural network  Asif Khan, Dae-Kwan Ko, Soo Chul Lim*, Heung Soo Kim* (* : corresponding author) Abstract This paper proposes a Convolutional Neural Network (CNN) based approach for the classification and prediction of various types of in-plane and through-the-thickness delamination in… 더 보기 »Journal Paper Accepted (Composites Part B: Engineering): Structural vibration-based classification and prediction of delamination in smart composite laminates using deep learning neural network

AbstractProvided is an apparatus and method for controlling a vibration transfer between vibration devices. The apparatus for controlling a vibration transfer may change vibration values of a plurality of vibration devices according to a movement of a virtual vibration body, thereby providing a user with a sense of touch of a movement of the virtual… 더 보기 »US patent 등록 “Apparatus and method for controlling vibration transfer between vibration devices”, US10152127

Interaction Force Estimation using Camera and Electrical Current without Force/Torque Sensor Dong-Han Lee ;  Wonjun Hwang ;  Soo-Chul Lim Abstract: In this paper, we propose a method for the estimation of the interaction forces between the motorized system and object through visual and electric information. In particular, we propose a new interaction force sensing method… 더 보기 »Journal Paper Accepted (IEEE Sensors Journal): Interaction Force Estimation using Camera and Electrical Current without Force/Torque Sensor

Mechanical Vibration Influences the Perception of Electrovibration Semin Ryu, Dongbum Pyo, Soo-Chul Lim & Dong-Soo Kwon   Abstract Recently, various methods using, simultaneously, two types of tactile feedback have been proposed to emulate a real object. However, the possible masking effect when providing two types of tactile feedback has been scarcely reported. In this study,… 더 보기 »Journal Paper 게재(Scientific Reports) : Mechanical Vibration Influences the Perception of Electrovibration

Compact Hip-Force Sensor for a Gait-Assistance Exoskeleton System Hyundo Choi 1, Keehong Seo 1, Seungyong Hyung 1, Youngbo Shim 1 and Soo-Chul Lim 2,* Abstract In this paper, we propose a compact force sensor system for a hip-mounted exoskeleton for seniors with difficulties in walking due to muscle weakness. It senses and monitors the delivered… 더 보기 »Journal Paper 게재(Sensors) : Compact Hip-Force Sensor for a Gait-Assistance Exoskeleton System
