Research paper thumbnail of Electrical Properties and DC Conductivity of Phosphoric Acid Doped TGS Single Crystals

Research paper thumbnail of Design and control of an actuated thumb exoskeleton for hand rehabilitation following stroke

Chronic hand impairment is common following stroke. This paper presents an actuated thumb exoskel... more Chronic hand impairment is common following stroke. This paper presents an actuated thumb exoskeleton (ATX) to facilitate research in hand rehabilitation therapy. The ATX presented in this work permits independent bi-directional actuation in each of the 5 degrees-of-freedom (DOF) of the thumb using a mechanism that has 5 active DOF and 3 passive DOF. The ATX is able to provide considerable joint torques for the user while still allowing backdrivability through flexible shaft transmission. A prototype has been built and experiments were conducted to evaluate the closed-loop position control. Further improvement and future work are discussed.
