Bionic Superhumans: The exciting Future of Prostheticswhat the
By Patrick Kane. Thu 15 Nov I was born with the usual set of limbs. When I was nine months old, I contracted meningococcal septicaemia, a dangerous infection of the blood, which very nearly killed me. I survived, but because I had sustained major tissue damage, it became necessary to amputate my right leg below the knee, all of the fingers on my left hand and the second and third digits on my right hand. I learned to walk on a prosthetic leg at the age of 14 months, and have gone through my life wearing a succession of artificial limbs. As time has passed and technology has advanced, so too have my limbs.
Bionic arms such as the Hero Arm are worn by people with upper limb differences, like Kate , Dan and Raimi. When a user puts on their bionic arm and flexes muscles in their residual limb just below their elbow; special sensors detect tiny naturally generated electric signals, and convert these into intuitive and proportional bionic hand movement. The bionic hand is controlled by tensing the same muscles which are used to open and close a biological hand. To open the hand, imagine extending the wrist with an outstretched palm. The technology is known scientifically as electromyography, and the special sensors in bionic arms are electromyographical, or EMG, electrodes. Myoelectric bionic arms are plug and play, meaning users can take their bionic arm on and off with ease.
The person behind it is just as mysterious: Samuel M Samuel is in the business of bionics, and currently working on making affordable bionic prosthesis that will restore functionality to amputees. Moving away from current technology, M has spent the last 20 years researching and developing an artificial muscle actuator, with the hope of disrupting the current state of robotics. Exposed to scientific concepts of fine art at an early age through his father, M has long been inspired by the studies of human anatomy and biomechanics pioneered during the Renaissance. However, most importantly M is a dreamer, which he claims is a characteristic he acquired from his mother who encouraged him to believe that anything was possible. Can you tell us a little about yourself and what it is that you do? Samuel M: I am a garage tinkerer, the guy that comes out of left field, I am a dreamer. I believe mankind has such an incredible, untapped potential.
Bionics or biologically inspired engineering is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. The word bionic was coined by Jack E. Steele in August , being formed as a portmanteau from bio logy and electro nics. All feature humans given superhuman powers by electromechanical implants. The transfer of technology between lifeforms and manufactured objects is, according to proponents of bionic technology, desirable because evolutionary pressure typically forces living organisms, including fauna and flora, to become highly optimized and efficient.

How does a bionic arm work?
From the first steps, projects had been directed on the solution of a problem of development of the domestic bionic functional artificial limb of the hand based on neural network and others algorithms. In projects, it had been created the functional system of management, system of tactile feedback which has increased controllability of a functional artificial limb is already realized and integrated, and also the functional bionic artificial limb of the hand. Based on this work it had been done the general representations and practical application of machine training, neural network and others algorithms. The technology of recognition of gestures of electromyographic activity based on neural network or an analog of network is the cornerstone. The bracelet is put on a hand in case of disabled people, a stump , further noninvasive electrodes remove potential difference of neuromuscular activity; by means of an electric circuit there is data handling and their transmission to the processor where by means of a neural network there is a recognition of a gripper, further data are transferred for control of a bionic hand.
Thirty plus years ago Bionics was just a part of science fiction. Today, it might just be possible. Every year, the discoveries made are having profound effect on the lives of people all around the world. If we look at some interesting examples regarding Bionics, 30 years ago, the potential for deaf children to communicate verbally was greatly diminished. Now with bionic ears and educational support, people with even a profound hearing loss can speak clearly and confidently. Bionic eyes have already restored basic sight for people with certain conditions, artificial limbs now became a reality and other advances are now on the horizon.

When you reach your hand out to grab your coffee cup or another object, your brain is signaling certain muscles to move. As your hand moves in response, nerves for those muscles send a message back to the brain about the movement.
