  In this paper, a different approach on the use of the ADS1299 (an analog
front-end with features for electroencephalogram and electrocardiography signal
acquisition) is considered, proposing the development of a surface
electromyography (sEMG) device. The main features of the device include
simultaneous recordings of eight muscular channels, wireless transmission and
virtual instrumentation with the use of LabVIEWTM software. The proposed sEMG
device contains a specifically designed protocol to accommodate data
transmission by reducing the data size while still delivering adequate
resolution (34.33 uV), amplitude range (17.57 mV) and sampling rate (1000 Hz)
for sEMG signals. For the validation methods, a generated sine wave and a known
sEMG data were evaluated. Moreover, the muscular recordings for all the eight
channels of a human arm were successful and the results expose the isolated
contractions of the triceps and the biceps with their amplitude range and
frequency spectrum.
