Description

What is MRE?
•MRE is a semi-active silicon with embedded iron particles for variable stiffness changes under external magnetic flux

Research Objective
•Feasibility of using MRE as a haptic feedback device.
•Design a MRE device that can increase or decrease the stiffness.
•Design an effective way of providing a “pre-strain” to the base silicon material.

Computational Simulation
•COMSOL 4.3b Finite Element Analysis
•2D axisymmetric model
•Parametric sweep was run to find the amount of current needed to counteract the permanent magnet.
