Summary

For hundreds or even thousands of years, humans have developed ever lighter and stronger materials, including alloys, polymers, and composites. Recently, these efforts have been joined by a different approach to lightweight materials: the introduction of carefully engineered open structure into solid materials to create cellular materials (see the figure). On page 1219 of this issue, Cheung and Gershenfeld (1) present a fabrication method for cellular materials that enables them to reversibly assemble cellular composite materials with tailored properties.
