Cover Story: As one of the most important prosthetic implants for amputees, commercially available prosthetic hands are too bulky, heavy, expensive, complex and inefficient. We present a study that utilizes artificial tendons to drive the motion of fingers in a biomimetic prosthetic hand. The artificial tendons are realized by combining liquid crystal elastomers (LCEs) and liquid metal (LM) heating elements. Joule-heating-induced temperature increase in the LCE tendons leads to linear contraction, which drives the fingers of the biomimetic prosthetic hand to bend in a way similar to the human hand. This biomimetic prosthetic hand is demonstrated to be able to perform complex tasks, including making different hand gestures, holding objects of different sizes and shapes, and carrying weights.
