MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202611073974 A) filed by Chandigarh University on June 15, 2026, for Adaptive Magnetorheological Nanofluid Coupling System With Variable Stiffness And Torque Transmission.
Inventors include Priyansh Sharma; Akshit Chaudhary; and Dr. Kamaldeep Kaur.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The invention relates to an adaptive mechanical coupling system comprising a primary mechanical member, a secondary mechanical member, a sealed coupling chamber, a magnetorheological nano-fluid disposed within the chamber, and an electromagnetic field generation unit. The electromagnetic field generation unit is configured to generate a magnetic field within the coupling chamber, causing magnetic nanoparticles present in the nano-fluid to align and form reversible structures capable of transmitting torque between the primary and secondary mechanical members. The coupling characteristics are selectively varied by controlling the magnetic field strength. The system is configured to provide variable stiffness, adaptive damping, shock-responsive stiffening, and directional torque transmission. In certain embodiments, the coupling chamber comprises multiple independently controllable fluid regions configured for load redistribution and fault tolerance. The system further includes impedance-based sensing means for monitoring coupling conditions. The invention is applicable to robotic, industrial, aerospace, marine, and defence systems.
