New 3D-printed muscle can lift 1,000 times its own weight
Columbia University researchers have developed a 3D-printable soft muscle with intrinsic expansion ability which does not require a high voltage equipment. The material can expand 15 times more than natural muscle and can lift 1,000 times its own weight. The prototype showed 900% expansion when electrically heated to 80ÂºC and could be used for making "lifelike" robots, said researchers.
