Abstract

Although superficial electromyographic signals are the most common input signal for machine learning algorithms in hand gesture recognition and finger force estimation applications, there are only a few commercially available systems for superficial EMG acquisition. This work proposes a cheap and easy to fabricate, dry superficial electrodes array. This system uses multiple active differential sensors integrated in a small double layer PCBs, each one uses two small rectangle areas of the bottom layer as conductive layer for signal acquisition. With a differential gain of 60dB between 23 and 3000Hz and a common mode rejection ration of -60dB at 60Hz. Design criteria and simulations are presented.
