During photosynthesis, natural leaves with elaborate architectures and functional components can harvest and convert solar energy into chemical fuels that are converted into energy. The biological energy production has provided materials scientists a new bioinspired paradigm to produce many autonomous systems, including light-triggered motion. In a recent report, Guofo Cai and co-workers at the departments of Materials Science and Engineering, Astronautic Science and Mechanics, and Chemical Engineering, developed an unprecedented bilayered actuator base on MXene (Ti3C2Tx)-cellulose composites (MXCC) and polycarbonate (PC) membranes.
