A Self-Tunable Dynamic Vibration Absorber: analysis, modulation and simulation for Parkinsonian tremors

Ver documento

Detalhes bibliográficos
Resumo: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.
