Electromyography is of great importance for the study of muscles and their motor function. This discipline deals with the detection, analysis and use of electrical signals that emanate from muscle contractions, known as myoelectric signals. The equipment for acquiring this type of signal is usually complex and has a high cost. Therefore, in recent decades, research has sought to develop simpler and less costly devices. This work proposes the design and construction of a low cost system, with multiple channels, to capture myoelectric signals. The system uses surface electrodes and is divided into an analog and a digital stage. With this, it is possible to send the signals to a computer so that they are displayed and stored. It is expected that this system, due to its ease of use, good acquisition quality and reduced cost, will be used in future academic research.
