It is amazing what science fiction combined with real-life wonders can inspire. The invisible man – totally fiction? Maybe not anymore. Materials inspired by disappearing Hollywood dinosaurs and shy squid have been molded into a new invention by UCI engineers, making them the beginning of what could be the first step toward invisibility cloaks.
The thin swatches can quickly change how they reflect heat, smoothing or wrinkling their surfaces in under a second after being stretched or electrically triggered. That makes them invisible to infrared night vision tools or lets them modulate their temperatures.
“Basically, we’ve invented a soft material that can reflect heat in similar ways to how squid skin can reflect light,” said corresponding author Alon Gorodetsky, an engineering professor. “It goes from wrinkled and dull to smooth and shiny, essentially changing the way it reflects the heat.”
Potential uses include better camouflage for troops and insulation for spacecraft, storage containers, emergency shelters, clinical care, and building heating and cooling systems.
“We were inspired both by science fiction and science fact – seeing dinosaurs disappear and reappear under an infrared camera in Jurassic World and seeing squid filmed underwater do similar things,” said Gorodetsky. “So we decided to merge those concepts to design a really unique technology.”
Made of sandwiches of aluminum, plastic, and sticky tape, the material transforms from a wrinkled grey to a glossy surface when it is either pulled manually or zapped with voltage.
Products that reflect heat, such as emergency blankets, have existed for decades. But in the past several years, inventors in Gorodetsky’s lab and others have pushed to create dramatically improved versions via bio-inspired engineering. One focus has been to imitate how squid and other cephalopods can nearly instantaneously change their skin to blend into their surrounding environment.
Now, he and his team have done it, creating prototypes that can next be scaled up into large sheets of commercially useable material. Patents are pending.
“It was hard, especially the first phase when we were learning how to work with the sticky material,” said doctoral student Chengyi Xu, lead author. After trial-and-error processes involving thousands of attempts, he and postdoctoral scholar George Stiubianu finally saw the mirror-like coating change when they pulled it sideways.
“The whole project was so exciting.” he said.
Exciting is definitely the perfect word for it. Who knows what they will come up with next!
I write like I think—fast, curious, and a little feral. I chase the weird, the witty, and the why-is-this-happening-now. From AI meltdowns to fashion glow-ups, if it makes you raise an eyebrow or rethink your algorithm, I’m probably writing about it. Expect sharp takes, occasional sarcasm, and zero tolerance for boring content.
