Recent advances in preprogrammed architected materials could enable new functions that can evolve in response to their environments or external stimuli, according to Lawrence Livermore National Laboratory (LLNL) researchers.

In a paper published by Nature Reviews Materials, LLNL researchers provide an overview of the progress made in responsive architected materials that can morph into a particular shape and exhibit new properties when exposed to heat, magnetic or electrical forces, chemical or electrochemical reactions, and mechanical deformations. The authors also explain the programming and transformation mechanisms of each approach and examine potential applications, including implantable medical devices, robotics, and chemical or mechanical sensors. The journal will feature the paper on the cover of an upcoming print edition.
