Acquisition and Conditioning of Electromyographic Signals for Prosthetic Legs

The Surface Electromyography (SEMG) is a technique used for many applications in different areas such as: Neurology, Rehabilitation, Orthopedics, Ergonomics, Sports, etc. [15]. In the last years, this technique has led to great research, and several groups of researchers throughout the world have made inroads in the field of the electromyography applied to the my electric prostheses control. This project aims to detail the stages of amplification and filtering of a my electric signal, as well as to check the device´s function for certain muscles of the lower limbs, as the project´s first stage, the completed tests were made with obtained data in healthy subjects. For the circuits´ design and implementation, components of easy acquisition and existents in the environment, were used, contributing with the technological development of the country.
