A joint research team from POSTECH, Eunpyeong St. Mary’s Hospital, and Hankuk University of Foreign Studies has developed a 3D-bioprinted retina-on-a-chip and retinal vein occlusion model.
A new method developed at the University of Warwick offers the first simple and predictive way to calculate how irregularly shaped nanoparticles — a dangerous class of airborne pollutant — move through air.
The Korea Research Institute of Standards and Science (KRISS, President Lee Ho Seong) has developed an artificial intelligence (AI)-based image segmentation algorithm that can rapidly reconstruct three-dimensional (3D) structures from two-dimensional (2D) cross-sectional images of biological samples captured using a scanning electron microscope (SEM).
The Advanced Robotics Research Center at the Korea Institute of Machinery and Materials (KIMM, President Seog-Hyeon Ryu), under the National Research Council of Science & Technology (NST, Chairman Young-Shik Kim), led by Principal Researcher Cheol Hoon Park, has developed an automated weaving system that enables the continuous mass production of fabric muscle, a lightweight yet powerful artificial muscle actuator.
This study presents a bio-inspired linear-to-torsion vibration isolator mimicking the square tail exoskeleton of seahorses. The seahorse-exoskeleton-inspired structure (SES) uses two oblique rods, two springs, and a rotational disc to convert incoming linear motion into disc torsion, creating tunable nonlinear stiffness, equivalent mass, and damping. A full geometric and dynamic model (via Lagrange formulation and harmonic balance) guides design across devices and loading conditions. Experimental validation showed that the SES achieved a peak frequency as low as 1.48 Hz and exhibited anti-resonance due to torsional inertia; its nonlinear damping increases with input amplitude, yielding stronger isolation under larger excitations. Together these results point to compact, adjustable isolators for precision machines and other low-frequency environments.
