# Magnetorheological Fluid

Fluids that change viscosity under magnetic fields for adaptive damping and control systems
- Technology Readiness Level: 6/9
- Impact: 4/5
- Investment: 3/5
Magnetorheological (MR) fluids change viscosity in response to magnetic fields, enabling controllable damping. Limited commercialization in MR dampers for vehicles and structures; research continues into seismic damping for earthquake resistance. Applications include suspension systems, brakes, and adaptive structures.
