The folding of circular rings has shown bistable snap\u2010through deformation under simple twisting motion and demonstrates a large area change to 11% of its undeformed configuration. Motivated by the large area change and the self\u2010guided deformation through snap\u2010folding, it is intended to design ring origami assemblies with unprecedented packing ratios. Herein, through finite\u2010element analysis, snap\u2010folding behaviors of single ring with different geometries (circular, elliptical, rounded rectangular, and rounded triangular shapes) are studied for ring origami assemblies for functional foldable structures. Geometric parameters' effects on the foldability, stability, and the packing ratio are investigated and are validated experimentally. With different rings as basic building blocks, the folding of ring origami assemblies including linear\u2010patterned rounded rectangular rings, radial\u2010patterned elliptical rings, and 3D crossing circular rings is further experimentally demonstrated, which show significant packing ratios of 7% and 2.5% of the initial areas, and 0.3% of the initial volume, respectively. It is envisioned that the reported snap\u2010folding of origami rings will provide alternative strategies to design foldable\/deployable structures and devices with reliable self\u2010guided deformation and large area change.<\/jats:p><\/jats:sec>","DOI":"10.1002\/aisy.202100107","type":"journal-article","created":{"date-parts":[[2021,7,31]],"date-time":"2021-07-31T05:22:12Z","timestamp":1627708932000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Ring Origami: Snap\u2010Folding of Rings with Different Geometries"],"prefix":"10.1002","volume":"3","author":[{"given":"Shuai","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Mechanical and Aerospace Engineering The Ohio State University  Columbus OH 43210 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liang","family":"Yue","sequence":"additional","affiliation":[{"name":"The George W.
