Self-folding origami machine powered by chemical reaction
Cornell University led a collaboration that harnessed chemical reaction to make microscale origami machine self-fold. This freed them from liquids, in which they normally function. They can now operate in dry environments at room temperature.
This approach could lead to a fleet of tiny, autonomous devices capable of responding quickly to their chemical environments.
The paper by the group, \”Gas Phase Microactuation using Kinetically Controlled surface States of Ultrathin catalytic Sheets\”, was published in Proceedings of National Academy of Sciences on May 1. Nanqi Bao Ph.D., ’22 and Qingkun Liu Ph.D., ’22 are the paper’s lead authors.
