Summary:Main objective of this work is designing and implementation of low cost electromyography (EMG) signal acquisition system which provides multichannel facilities. The major challenges of this work are to meet the quality as well as the cost at the same time. Our designed acquisition system comes with some attractive features like real time data display, offline data store, and simultaneous use of three channels. This multiple channel acquisition system is implemented using instrumentation amplifier (INA118) for pre-amplification stage. For smoothing and rectification purposes operational amplifiers (TL 072) have been used. In this system, 10 bit analog to digital (AD) converter of Arduino UNO has been used. Then the output data are displayed graphically by using open source software named by Serial Oscilloscope. The acquired data is validated by two ways. At first, the acquired data is used to control the prosthetic hand. Else, the acquired data by this designed acquisition system has been compared with certified Biopac Mp36 system and we have achieved 84.1% correlation coefficient. These two validation test proves the effectiveness of our designed system. In addition with that, the cost of this data acquisition is only 40 USD.
