Contents I. Introduction
Loss of a limb is a drastic occurrence for people and society, particularly for the upper limb, due to the fine motor task performed by the arm and the hand. Advancement of technology had led to developments in the various fields of science, which includes the field of medical technology. The conceptualization of prosthetics came about in the 900th B.C when the first prosthetic toe was created and the field has since seen significant improvements in terms of upgrading its functionality and aesthetics. Prostheses have been developed to assist restore the lost features to a physical loss [1]. In the context of prosthesis, various kinds of system are developed to be integrated into prosthesis; most of these types are categorized in terms of its design and its source of energy to produce movements. The several types of upper limb prostheses designed according to amputee different activities. The wide range of prostheses for replacement the hand can be classified into passive and active prostheses. In passive prosthesis, the external force applied to adjust the mechanism. While in active prostheses, the force used to control the grasping mechanism of active prostheses is applied internally, such as by an electric actuator or a body-powered cable. [2].
