Abstract: A hybrid prosthetic hand is detailed which is controlled via input from both sEMG signals, as well as mechanical control from the elbow and shoulder of an amputee. The device is equipped with mechanical fingers, which are driven by electrical motors, and controlled via microcontrollers. The mechanical fingers are designed to form a variety of shapes and provide variable force in accordance with the contextual desires of the amputee, which are conveyed to the device primarily through the movement of the shoulder and/or elbow of the amputee. The instructions sent to the mechanical fingers of the device by the shoulder or elbow is augmented by instructions provided via sEMG signals.
