Magnetorheological fluids based haptic device Available to Purchase

This paper presents the development of a haptic device working with magnetorheological (MR) fluids. The computer screen is portioned in various segments and the controllable software monitors the attributed values of the voltage to the screen. The motion of a cursor on the computer screen is controlled by the MR actuator. A resistance force, the strength of which depends on the cursor position, would be generated and perceived by the user. The performance of the device is tested and verified with finite element analysis.
