Quick Summary
Additional Context
Researchers from Korea’s Pusan National University and Oak Ridge National Laboratory (ORNL) have developed 3D printed elastomeric actuators. In a paper published in Nature, the team used elastomeric liquid crystal filaments. The filaments were printed while changing their molecular orientations, letting them either expand or contract, and enabling switchable actuators.
The team consisted of Jin-Hyeong Lee, Kyeong Pyo Kim, Lijie Ding, Michael Li, Min Chan Kim, Kyu Hyun, Ji Hoon Kim, Jan-Michael Y. Carrillo, and Suk-kyun Ahn, all from Pusan’s School of Chemical Engineering and School of Mechanical Engineering. On the ORNL team, researchers joined from the Neutron Scattering Division & Center for Nanophase Materials Sciences. So here we’re seeing a multinational team, from very different dis
