Researchers from the Korea Advanced Institute of Science and Technology (KAIST), Pusan National University and CNRS have developed an artificial muscle that is 17 times more powerful than that of humans. The muscle made of graphene-liquid crystal elastomer-based fiber bundles will reportedly be commercialized through a Korean company. Image The main factor that hinders the development of high-performance artificial muscles is that scientists are not able to mechanically select a certain part of the artificial muscle to contract and expand. Large and bulky artificial muscles are not accurate enough.
