2D Lattice materials for low energy actuation

Abstract

In the last two decades, lattice materials have received considerable attention as a means to design adaptive (shape morphing) structures [1-5]. Similar to foams, lattice materials are lightweight, but can be much stiffer and stronger depending on their microarchitecture. Externally triggered lengthening or shortening (actuation) of one or more members in a lattice material can be used to achieve significant macroscopic shape change.
