gForcePro+ EMG Armband

There are 8 surface EMG sensors embedded throughout the gForce armband. The main hub contains sensor 1 and the USB port. With the USB port facing the user, in a clockwise direction, are sensors 2 through 8, as shown in the following diagram. Each EMG sensor has three stainless dry electrodes. The one in the middle is the reference electrode. The two electrodes on its both sides are one differential pair. The electronics inside together with the three electrodes build up one surface EMG sensor. It monitors and amplifies the potential difference on the two electrodes, then together with the other sensors are digitized.
