Abstract
Some physiological conditions or neurodegenerative diseases, such as Parkinson’s disease, often cause tremors in the wearer’s limbs. This tremor is almost always associated with social discomfort and difficulty performing some movements. This work aims to establish an analysis of the efficiency of vibration control in an arm of a patient with Parkinson’s disease. However, the operating logic of the control used is extracted from the technology reported in the patent document Moura and Machado (2022). This technology is capable of promoting programmable attenuation and band gaps using a piezoelectric beam meta-structure connected to a resonant shunt circuit. In resume, the present work intends to use this technology to compare and elucidate the best amount of coupling of shunt circuits to be able to attenuate a vibration mode of the arm, emphasizing a possible control saturation limit.
