Abstract :
In this article an attempt has been made to give some ideas about intelligent bionic hand that can improve performance of existing bionic hand and will lead to extend future of bionic hand structures. Some of ideas are based on current bionic hand projects which they work by taking impulses from nerve stubs of amputee´s limb. Although all of projects are using high technology but they are not completed yet and need to some changing to act reliable and accurate that can give patients feel of having real limb or maybe he or she can feel they don´t have limitation because of their amputated limb. Technology of some ideas currently is available but others do not achieved completely and needs time to develop. This paper provides an overview of different type of methods which control bionic hand joints and knuckles motors by control software that work by analyzing patient feedbacks and adjust its functionality by guessing best and preferred motions, moreover, some of methods contain software changing and embedding into its current control software which mainly worked by record and analyze feedbacks and creates ideal motion models for each limb´s part by processing feedback database information, as well, hardware parts which get its performance higher such as touch sensors and microphone should be added also there is some idea for its energy supplying. The goal of this paper is to outline ways which by applying them bionic hand can have precise motion or their performance will be improved and make them closer to organism hand motion.

The most common forms of bionics are artificial limbs and artificial organs. In medicine, bionics means the replacement or enhancement of organs or other body parts by mechanical versions. Bionic implants differ from mere prostheses by mimicking the original function very closely, or even surpassing it; Cyborg: The cybernetic organism is the biological organism that has the mechanical components but as robots it has the biological components. In other words the cyborg is the example of the biological and mechanical combination; Myoelectric: also called a motor action potential, is an electrical impulse that produces contraction of muscle fibers in the body. The term is most often used in reference to skeletal muscles that control voluntary movements. Myoelectric signals have frequencies ranging from a few hertz to about 300Hz and voltages ranging from approximately 10 microvolts to 1 millivolt; Photovoltaics: (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect; fMRI: Functional MRI is a magnetic resonance imaging (MRI)-based neuroimaging technique which allows us to detect the brain areas which are involved in a task, a process or an emotion;
