BIONIC PROSTHESES - FEATURES, KINDS AND POSSIBILITIES

Purpose: The purpose of this article is to introduce bionic prostheses and the signal detection technologies used to drive them. At the outset, the term prosthesis is defined, and a classification of prosthesis types is made. Ways of detecting signals from neurons using properties of electromyography and electroencephalography are discussed. The sequence of steps in the operation of a system using bionic technology to control a prosthesis is described. Finally, a brief description of the Open bionics hero arm version 12.0 prosthesis is given. Materials/Methods: The social aspect and need for the use of bionic prostheses is discussed. The types of prostheses are systematized according to their mode of operation, placement, purpose and functions. The most commonly used bionic signals are presented. An implementation model of a system using bionic technology is composed. The main factors causing inaccuracy and noise in recorded bionic signals are described. Results: The main technologies used in managing bionic prostheses include electroencephalograph and electromyograph. Various external factors can indicate an influence over the received bionic signal. Bionic prostheses have been created to replace a patient's upper limb, but as of now, they are unable to fully recreate its functions. Conclusion: The development and implementation of bionic technology in prosthetics would improve the social and domestic life of a patient with an amputated limb. Further research is needed on the use of bionic technology and refinement of techniques to remove external noises included in the received bionic signals.
