Significant advancements have been made in upper extremity prosthetics in recent years. Yet, the goal of independent digital control remains elusive, given the limitations of the human-prosthesis interface. Surface myoelectric signals must be detectable to power these prosthetics, and patients with partial or total hand amputations usually lack the requisite number of functioning, detectable muscles. As a result, patients often abandon the use of current myoelectric hand prosthetics due to the unnatural and nonintuitive ways of controlling them.
