From Jelly to Steel: Russian Scientists Develop Smart Fluid That Hardens on Command
19:41 19.09.2026 (Updated: 19:51 19.09.2026) Russian researchers from several institutes of the Russian Academy of Sciences and Moscow State University have developed a more stable magnetorheological fluid that can instantly change its stiffness under a magnetic field, opening new possibilities for adaptive machines and soft robotics.
The material consists of microscopic iron particles suspended in silicone; when exposed to a magnetic field, the particles align and transform the liquid into a solid-like state
Researchers solved a major stability problem by coating iron particles with a thin silica (SiO₂) layer, preventing them from clumping together or settling over time
Tests under magnetic fields of up to 1 tesla showed that the fluid’s viscosity and elasticity can rise by several orders of magnitude, allowing precise control over its hardness
The technology could enable soft robots, adaptive shock absorbers and other smart systems that automatically adjust their stiffness, bringing materials closer to artificial muscles that combine the flexibility of liquids with the strength of solids.
