Design of Mechanical Compensation System for Hand Tremor of The Old People

Physiological hand tremor is one of the common problems seen in old people. It is an involuntary action to perform activities precisely. In this paper, a flexure-based tremor compensation device is proposed as a table top that acts as a support for hand to suppress tremor. The flexure is designed based on the tremor dynamics data. FE simulation is conducted to study the performance of the flexure mechanism. Using the in-house developed tremor generation device, the flexure mechanism study was conducted and compared with the rigid base. The study shows that the flexure mechanism compensates for tremor better.
