A University of California (Irvine) team is pursuing the “ultralight material” trophy with this creation, a metallic microlattice that exhibits “complete recovery after compression exceeding 50% strain, and energy absorption similar to elastomers.”
Via The Atlantic, which calls it “the world’s lightest material” and adds:
The material, which is 100 times lighter than Styrofoam, is 99.99% air. The rest is a micro-lattice that can be made out of many materials, but the one in the above picture is composed mostly of nickel.
