"topological pumping: 4D synthetic metamaterial control mechanical surface energy vibrations of solids... civil engineering, micro-electromechanical systems (MEMS), national defense, quantum mechanics and quantum computing... by covering pillow-like structure in this material and placing it on Earth's surface underneath building could potentially help keep the structure from collapsing during an earthquake... passive metamaterial control sound wave paths as travel from 1 corner of material to another"
