A Self-Tunable Dynamic Vibration Absorber: Analysis, Modulation and Simulation for Parkinsonian Tremors

A Self-Tunable Dynamic Vibration Absorber (DVA) is proposed here as an alternative device for Parkinson´s Disease´s (PD) Tremor suppression. A hydraulic system that enables the DVA´s self-tuning using a control law was designed and implemented. Two different configurations for the DVA, un-dampen and dampen, were simulated using PD´s tremors collected by sensors in patients as the system´s input and results show oscillations reductions in the order of 50% and 80%, for the un-dampen and the dampen configuration respectively. The results are promising and demonstrate the self-tunable DVA´s potential as a wearable biomedical device for PD´s tremor suppression and for other type of neurological tremors.
