Patent Images
1. A sensor system for detecting and processing EMG signals comprising:
- a substrate having a bottom surface adapted for attachment to skin;
a plurality of spaced apart electrodes projecting from said bottom surface so as to engage the skin and detect EMG signals in muscles located under the substrate; and
a plurality of differential amplifiers connected to receive EMG signals from pairs of said electrodes, wherein at least two of said pairs of electrodes are arranged in a radial pattern.

Abstract
A sensor system for detecting and processing EMG signals including a substrate having a bottom surface adapted for attachment to skin; a plurality of spaced apart electrode arrays projecting from the bottom surface so as to engage the skin and detect EMG signals in muscles located under the substrate; and four differential amplifiers connected to receive EMG signals from four distinct pairs of electrode arrays. The electrode arrays detect the action potentials of the muscle fibers from various orientations so that the shape of an action potential appears substantially dissimilar in each of the four differential pairs.
