"Embodied logic and actuation control in soft, stimuli-responsive structures poised near bifurcation points" was invented by Jordan R. Raney (Glenside, Pa.), Lucia Korpas (Philadelphia) and Yijie Jiang (Corinth, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "Provided are devices and methods that combine material anisotropy with nonlinear structural design to produce structures that precisely and sequentially actuate in response to multiple stimuli, such as water or non-polar solvents. These devices and methods can include bistable anisotropic e...
