DESIGN OF A HANDHELD AND SMART DEVICE TO ATTENUATE HAND TREMOR BY ACTIVE AND PASSIVE CONTROL

In this paper an innovative device as a noninvasive Inethed to suppress the hand tretnor is studied. The usage of this device is as a spoon and caII help patients with hand tremor to eat with less difficulty. In this paper the design of mentioned device is discussed and its performance as a passive device is evaluated. Then to improve applicationof the device for suppressing the hand tremor, an actuator is added to the system and an active control is applied to it. Then, performance of the device with active control isevaluated and discussed. Based on studies done in this research, by using the presented device for a hand path like it uses for eating, the passive system can attenuate theundesired hand tremor up to 55.39%. In similar situation. the hand tremor of patients using the equivalent device with active controller can be reduced up to 95.97%.
