Módulo de captação e condicionamento de sinais EMG com eletrodos secos

Abstract

Electromyography is the method used to detect electromyographic signals, these signals are used to assess the health of muscles and diagnose diseases or disturbances related to signal transmission from the nerve to the musculature. They are also used to assess muscle activation during an exercise and in the control of mechanical prostheses. The electromyographic signal is detected by an electromyograph that captures the muscular electrical activity generated through movement and allows visualization on a graph. This work develops an EMG signal capture module. The module contains instrumentation differential amplifiers capable of maintaining the integrity of the amplified signal, bandpass filters and space reserved for the addition of a microcontroller. The dry electrodes of this module are directly integrated into the printed circuit board, without the need for soldering or connection by cables or pushbuttons. The choice of this type of electrode should improve the signal as it eliminates the interference generated by other types of electrodes.
