MR Fluid Haptic System for Regional Anesthesia Training Simulation System

摘要

Magneto-Rheological (MR) fluid is a class of controllable smart material whose rheological properties may be rapidly varied by the application of a magnetic field. In this paper we focus on our MR fluid based haptic system providing accurate haptic feedback for needle insertion and syringe injection. We use the essential characteristic of MR fluid, a controllable yielding strength in milliseconds under magnetic field, in our innovative MR fluids-based haptic feedback device that imposes simulated force for the regional anesthesia simulator.
