Upper Limb Tremor Suppression in ADL via an Orthosis Incorporating a Controllable Double

Viscous Beam Actuator

• Design and testing of an orthosis incorporating a novel actuator based on MR fluids.

• Modelling, implementation and validation of tremor suppression algorithms.

• Preliminary results for subject with ET using 4Ns/mm damping coefficient: – tremor suppression approx. -43dB at 4Hz, voluntary

motion -17dB at 1Hz.
