Determining a biopotential of deep layer muscles includes arranging electrodes on skin of a subject in a pattern corresponding to muscle tissue fibers of the subject, electrically coupling a subset of the electrodes to form a common reference node having a reference potential, and determining bipotential signal differences for separate electrodes that are not members of the first subset. For each of the separate electrodes, a biopotential difference is determined between a biopotential detected by each of the separate electrodes and the reference potential. An extent of the biopotential difference attributable to at least one deep-layer muscle is determined based on the biopotential differences. The pattern may be a two-dimensional array having columns of the electrodes arranged in a first dimension parallel with the muscle tissue fibers and a plurality of rows of the electrodes arranged in a second dimension that is orthogonal to the first dimension.
