A 3-D printed prosthetic hand can be wired to respond to signals from the muscles of the forearm, scientists report in Science Robotics on June 26. By interpreting the forearm muscle signals using electromyograph (EMG) measurements, the device can move its fingers. Hand amputee and non-amputee study participants wearing the prosthetic hand can move its digits and pick up small objects.
