๐ง Miniature Magnetorheological Fluid Device Using Cylindrical Rotor for Handheld Haptic Interface ๐ค✨ ๐ Introduction The Miniature Magnetorheological (MR) Fluid Device with a cylindrical rotor represents a cutting-edge innovation in handheld haptic interface technology . By exploiting the smart rheological behavior of MR fluids—whose viscosity changes instantly under a magnetic field—this device enables precise, controllable tactile feedback. Its compact structure and fast response make it ideal for next-generation portable haptic systems used in virtual environments and human–machine interaction ๐ฎ๐️. ๐งช Magnetorheological Fluid Fundamentals MR fluids are suspensions of micron-sized magnetic particles dispersed in a carrier liquid. Key characteristics include: ⚡ Rapid response (milliseconds) ๐ Reversible viscosity change ๐ฏ Precise force controllability When exposed to a magnetic field, particles align to form chain-like structures, significantly increasing...
