Chemical Reactions Spark Life Into Self-Folding Micro Origami Machines
An SEM image shows an origami tetrahedra microstructure that self-folded after it was exposed to hydrogen. Credit: Cornell UniversityCornell researchers have devised a way to utilize chemical reactions for the self-folding of microscale origami machines, allowing them to work in dry, room-temperature conditions. This breakthrough could pave the way for the creation of tiny, autonomous devices that rapidly respond to their chemical surroundings.A Cornell-led collaboration harnessed chemical reactions to make microscale…
