Scientists at IIT Patna have developed an innovative hybrid magneto-rheometer to advance the testing and application of Magnetorheological (MR) fluids, a type of smart fluid.
Key Details
Magnetorheological (MR) fluids are smart fluids that quickly change from a liquid into a solid-like gel when exposed to a magnetic field. This property is harnessed in shock absorbers, vibration control systems, dampers, actuators, and medical devices.
The custom-built instrument, measures both rheological (flow and deformation) and tribological (friction and wear) properties of MR fluids in a single setup.
It evaluates fluid performance under simultaneous compression and shear forces, which mimics real-world conditions better than conventional testers.
The device operates with low electrical current while generating a constant, high-strength magnetic field, making it energy-efficient and reliable.
