People who suffer from Essential Tremor or Parkinson's disease have trouble performing daily tasks such as eating, drinking and writing, leading to weight loss and even depression in some situations. It causes social embarrassment and functional incapacity, being responsible for about 25% of the changes of work or distance of the same. Treatment of tremors it is ineffective in about 25% of patients has side effects with the use of drugs and can cause hemorrhages and psychiatric manifestations in neural treatments. In order to bring new therapeutic options to control tremor, the present work aims to develop a non-invasive tremor attenuation device with the use of inertia flywheels. An experimental model was developed to simulate the tremors composed of servo motor and two inertial wheels and, with the use of inertial sensor and Arduino, analyzes of tremor behavior were done according to the inertia flywheel. The acquired data showed that the tremor was attenuated by about 28%. Lastly, a printed glove was developed in 3D printer, in which two flywheels were coupled, being a feasible alternative in the non-invasive treatment of tremors.
