 The Technology Behind The Fabrication Of Prosthesis

In a time when the frontiers of technology are getting expanded by leaps and bounds, there is a need to envelop the sphere of bionics and prosthetics with the aid of scientific inputs. There has been a rapid advancement of architectural components as well as the overall design of prosthetic arms and hands in the last few years. Credit goes to advances in the domains of advanced neural networks that have enabled the state of art fabrication of prosthetic technology. As such, it becomes important to understand the technology behind the fabrication of prosthetic parts.

An overview of the control system

The most important part of the bionic arm is the user control system. There are three important sections of the control system of the bionic arm. The first is the technology control system while as the second one is the implicit control system. The third is the sensory feedback which helps in coordinating the overall movement. The technology control system can further be divided into four important parts. The first is called the myoelectric control which can be controlled directly by the user. The second is called the myoelectric pattern recognition. The third important part is also related to pattern recognition but needs to be surgically implanted with the help of sensors. Finally, the fourth important part represents neural interfaces that mainly rely on artificial intelligence to simulate the functioning of the human hand.


Most of the bionic hands available in the market make use of the myoelectric control. Myoelectric hands offer various grip patterns that are easy to use. However, the most important requirement of myoelectric control is the demonstration of control by the user. The advantage of the myoelectric control is its simplicity as well as cost effectiveness. The disadvantage is the latency which can be encountered while trying to form a grip around objects that have a complex curvature. In the present times, the functioning of the myoelectric component has been enhanced with the help of surgical techniques like targeted muscle reinnervation. This technology is especially suited for those candidates that have weak muscles and suffer from constant limb pain.

The most important advances that we are seeing in bionic technology are with the help of neural interfaces. Neural interfaces present the most promising technology for improving sensory feedback. In addition to this, they can also be used to intercept signals in a way similar to nerve impulses. In this technology, the central nervous system is coordinated and prepared for touch and sensory intervention by generating signals from motor nerves.

The way ahead

At the end of the day, it is the choice of the user that matters the most. Although a large number of technological options are involved in the domain of bionics, the appropriate choice has to be made by the user depending upon his convenience. It needs to be ensured that the bionic part maintains perfect coordination with other parts of the body and provides synchronized movements that resemble the natural functioning of the limb.
