we create a family of origami-inspired cellular metamaterials which can be programmed to have various stability characteristics and mechanical responses in three independent orthogonal directions. … Our study provides a platform to design programmable three-dimensional metamaterials significantly broadening the application envelope of origami.
Metamaterials have interesting behaviors: they interact with waves (sound, light, radio) in interesting ways, and/or have weird mechanical properties (e.g. non-newtonian).
And, I’ve forgotten the term for “expands one way when compressed in the other”. What is it?
How can this work be generalized for more kinds of behavior?
