Tremor is an involuntary muscle movement, trembling, or shaking of the hands. Caused by either Essential Tremor (ET) or diseases like Parkinson’s and Dystonia, tremors often affect daily activities including feeding, drinking, typing, and writing. An experimental framework based on vibrations and dynamics has been developed with inspiration from the well-known gyroscopic boat stabilizers, i.e. Schlick stabilizer. In Schlick stabilizer, a high speed rotating disk has been used as a source of angular momentum, producing gyroscopic effect when an input torque caused by ocean waves applies on the boat. Using a rotating gimbal, this gyroscopic effect can be converted to a useful stabilizing torque which will eventually be in the opposite direction of incoming ocean-wave-induced torque, and thus help stabilize the boat. In our experiment, we test this stabilization technique at laboratory scale, where we attach a heavy pendulum to the main shaft of the gyroscopic system, and measure by means of accelerations how spinning flywheel creates resistive torques to oppose the swing of the pendulum, thereby bringing the pendulum to steadiness. Without disclosing any intellectual property, we state that this stabilizing framework has potential to reduce hand tremor of many patients in the US.
