Abstract :
Haptic devices compatible with functional magnetic resonance imaging (fMRI) could become an invaluable tool for the study of human brain functionality and motor learning. This paper presents a spherical two-degree-of-freedom (DOF) device made entirely from polymers and suitable for use within an MR environment. The design includes a 2-DOF force sensor for measurement and control of interaction forces. It can be actuated by wire transmission from a remote or well-shielded place. This paper presents the realized prototype and discusses its application as haptic joystick, and its extension for 2-DOF planar displacement for use as x-y-manipulandum as well as tactile stimulator for the fingertips
