-Professor Park Jae-young's Team Develops a Non-powered Stretchable Pressure Sensor and Smart Glove Capable of Monitoring and Controlling Fine Movements of the Fingers-

-Expected to Be Used in Various Industries Such as Intelligent Robots, AR/VR, Sign Language Interpretation, and Various Human-machine Interfaces-

-Published in the Prestigious International Academic Journal Nano Energy by Elsevier (IF:19.069)-

Professor Jaeyoung Park's research team (Department of Electronic Engineering) has succeeded in developing a toroidal pressure sensor based on frictional electricity that can continuously monitor the fine movements of fingers in real time even without power. The research team created a high-performance stretchable pressure sensor that can precisely measure the movements of fine fingers by using a nano-composite material made of fine pyramid structure arrays and Mxene/Ecoflex, which has elasticity, as the negative charge layer of the frictional electricity nanogenerator and the finger skin as the positive charge layer. The produced sensor has excellent sensing characteristics and mechanical robustness, so it can be applied to various industrial fields such as hand gesture detection and control systems, sign language interpretation systems, intelligent robots using human-machine interfaces, drones, games, VR/AR, etc.
