Squid skin inspires new material

“Ultra-lightweight space blankets have been around for decades, but the key drawback is that the material is static," said Alon Gorodetsky, UCI associate professor of chemical & biomolecular engineering. "We've made a version with changeable properties so you can regulate how much heat is trapped or released."

The researchers took design cues from various species of squids, octopuses and cuttlefish that use their adaptive skin to thrive in aquatic environments.

The skin cells can instantly change from minute points to flattened disks. "We use a similar concept in our work, where we have a layer of these tiny metal 'islands' that border each other," said Erica Leung, a UCI graduate student in chemical & biomolecular engineering.
