Optimal particle ratio to maximize the dynamic range of Magnetorheological Fluid (MRF) damper for prosthetic limb

Amputation is a process of removing part of the body through surgery. Common reasons for limb amputations include diseases, poor blood circulation to the limb and severe injuries. In order to assist amputees to lead a normal life, prosthetic limb - the artificial...

In order to assist amputees to lead a normal life, prosthetic limb - the artificial device that replaces missing body part, needs to be designed as close as human limb.
