1. Introduction

Practical developments of LLC "Bionic Natali" and LLC "Bi-oN EMG" companies' researches and creation of technology of management of limbs on recognition of signal EMG on the basis of neural network were presented in the current article, and also the use of the given technology at rehabilitation of people with loss of an extremity, after an acute stroke and even in the game sphere for children and young people, such as virtual reality, radio control by machine, quadcopters, etc. was presented. In the article the practical results of a research of feedback on the basis of EMG of signals at disabled people and people without loss of limbs are given.

Within the project of the LLC "Bionic Natali" company, the hi-tech bionic artificial limb which surpasses all domestic functional electromechanical and cosmetic artificial limbs in the Russian Federation has been developed and also will surpass foreign bionic artificial limbs in functionality by industrial production. Within the project the functional control system, the system of tactile feedback which has increased controllability of a functional artificial limb is realized and integrated and also the functional bionic artificial limb of the hand is developed.

Now, in most cases, in the absence of a hand, the cosmetic artificial limbs bearing in themselves only the cosmetic purposes are used, being, in fact, a hand model. Electromechanical artificial limbs which allow to replace partially functionality of a full-fledged hand are widespread poorly at present, have limited functionality, and also are available to still a limited circle of users. Especially, this situation is characteristic of Russia that is explained by the influence of several factors: the certain structure of schemes of social insurance causing an order of financing of prosthetics for the state account of low consumer ability of the people who have lost a hand and, of course, absence in the market of decisions in various price segments with the significant level of functionality.

In a prosthetic repair, active transition from static prostheses to robotic bionic is now observed; in the light of this, it is possible to allocate tendencies in creation of cheap and low-quality prostheses from the 3D press and on cheap accessories and also development of more expensive prostheses, but the second tendency is bound to larger problems available for a technological base, namely, small capacious accumulators, small drives, plateaus of processing, processors, and so on. But, despite all difficulties, the last conform to requirements which are exposed by the state at a prosthetic repair, namely, the long-term use of prostheses, 2–3 years.

As for the most electromyographic bracelet, a control system on the basis of EMG—that decision on his allocation in the separate project that has been made after the prototype has been created and the architecture of work of a bracelet became clear, namely, that the bracelet can work independently and he can be tied to any electronic product with Bluetooth for management of this product. By the results of the works done, the LLC "Bi-oN EMG" company has been open, and its application is found in the sphere of rehabilitation and game devices. It is important to note that the game sphere for children has been chosen in connection with market width and also the need to reduce the price of product cost.

requirement of rehabilitation of disabled people before use of bionic artificial limbs of hands, use of an electromyographic bracelet of LLC Bi-oN EMG is offered as option.

significant level of functionality.

The sensing technology of gestures of electromyographic activity on the basis of a neural 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 any electronic device with the set special software (the executive mechanism), back coupling is carried out from the executive mechanism to a bracelet by means of signal transmission of back coupling and on a bracelet the vibromotor is launched in action.
