MR Fluid (MRF) & MR Powder (MRP)
The smart materials allowing us to create haptic feedbck
MRM (MR materials or magnetorheological materials) are smart materials consisting of fine, magnetizable particles (typically iron) whose rheological properties change through the application of a magnetic field.
This change occurs in less than 0,5 milliseconds, more than 200 times faster than the blink of an eye. Once the magnetic field is removed, the MRM reverts to its unlinked state.
