굴곡이 가능한 다축관절기능의 검지 손가락 설계

It is necessary to develope the functional finger prosthesis with multi-axis joints which is used for pinching and griping. Also, to analyze the function of the thumb and index finger having an important role in the function of the finger prosthesis is essential too. Nowadays the finger prostheses including the electronic prosthesis is used to pinch a simple product. However it does not satisfy the requirement of various functions of the disabled. There are several robot hands with many degree of freedom, although it is not light weighted and minimum volume. A study of the finger prosthesis is required to overcome the problem of weight and volume. The finger prosthesis developed in this study can flex up to about 90° in the metacarpal phalangeal joint and the proximal inter phalangeal joint and the distal inter phalangeal joint which can't be achieved the grip motion before was developed. The weight of the prosthesis is optimized to minimize and this developed prosthesis can be used conveniently.
