Recently, there has been a noticeable increase in interest in solutions utilizing electrical signals accompanying muscle activity. Electromyography (EMG) is a technique for recording, analysis and evaluating the electrical activity produced by striated muscle. Its great popularity is due, among other, to the ability to measure with non-invasive electrodes (called as sEMG surface electromyography). However, the limitations of this method are the high costs of specialized measuring equipment, and in particular the systems of bioelectric signal preamplifier circuits. The work presents the design of a low budget EMG signal amplifier. It has been designed and validated in accordance with ISEK (International Society of Electrophysiology and Kinesiology) and SENIAM (Surface ElectroMyGraphy for Non-Invasive Assessment of Muscles).
