뇌졸중 환자의 손 고정장치 제어를 위한 다축 힘/모멘트센서 개발 = Development of Multi-Axis Force/Moment Sensor for Stroke Patient`s Hand Fixing System Control

다국어 초록 (Multilingual Abstract)

Stroke patients should exercise for the rehabilitation of their fingers, because they can`t use their hand and fingers. Their hand and fingers are fixed on the hand fixing system for rehabilitation exercise of them. But the hands clenched the fist of stroke patients are difficult to fix on it. In order to fix the hands and fingers, their palms are pressed with pressing bars and are controlled by reference force. The fixing system must have a five-axis force/moment sensor to force control. In this paper, the five-axis force/moment sensor was developed for the hand fixing system of finger-rehabilitation exercising system. The structure of the five-axis force/moment sensor was modeled, and designed using finite element method(FEM). And it was fabricated with strain-gages, then, its characteristic test was carried out. As a result, the maximum interference error is less than 2.43 %.
