A bionic arm is an artificial appendage that is attached to a body part in order to replicate its functioning. On the basis of the level of amputation, a bionic part may be wrist, elbow, hand, or an entire arm. There are also some most advanced bionic arms that are fabricated to cater to special disabilities and are customised in nature.
Configuration
The configuration and dexterity of the bionic device can be understood with the help of its mechanical design that enables it to work in a smooth manner. The configuration of a bionic device resembles closely to that of a human body part. For instance, let us consider the example of a human finger and a bionic part that is designed to ensure its full-fledged functioning. A very small linear motor is attached to the end which is connected to the joints. The linear motor performs the function of muscular movement while the joints perform the function of carpals and metacarpals. The joints are powered by a battery so that appropriate linking system is established to execute the required moment. The design of the entire system simulates the functions of the tendons with the help of a bar linkage system. Usually, there is one independent joint and two dependent joints to create the replica of a complex finger in a simplified way.
Most advanced bionic arm
The domain of bionics has undergone a paradigm shift in the last few years. Complex bionic structures have been conceived and the commercialization of the most advanced bionic arms is in progress. As such, it becomes important to understand the assembly of complex structures. The most important part of the assembly is a centralised motor that coordinates the functioning of the overall structure. There is also a worm as well as as a worm gear that help in flawless moment. A pin and a bearing is attached on the lower part of the worm gear to enable it to co-ordinate with the lower assembly. The lower assembly comprises bearings as well as openings for cables.
Although the bionic arm is complex in its configuration, it is very smooth in its functioning and is able to provide a natural grip on objects much like its biological counterpart. The dexterity of the bionic arm enables it to coordinate with other body parts with the help of sensors and electrodes that are fitted within it. In addition to this, the architectural components of the bionic arm are designed to perform a large number of tasks and activities in a way similar to the natural arm and natural hand.
Concluding remarks
The bionic arm is indeed a remarkable feat of engineering and electronic technology with the sole goal of progressive social impact. The bionic arm has really made the life of amputees more fulfilling and engaging in nature. More research is needed in this domain to pave the way for further breakthroughs in bionic technology.
