Tree-frog inspires new super glue
Tree-frog inspires new super glue
Inspired by the toe pads of tree frogs and crickets, researchers
in India have created a form of sticky coating that is both strong and
reusable.
Animangsu Ghatak and his colleagues added tiny fluid vessels in their model adhesive and found they increased adhesion by 30 times.
“These fluid vessels, because of the capillary pressure, the adhesion stress increased by 30 times,” Ghatak said.
The team hopes to use their technology on stickers for utensils and food so that they may be peeled off cleanly, and on other adhesive devices that are meant to be reused.
“One application is for stickers on utensils, fruit, where you want to remove them cleanly, you don’t want the adhesive to remain on them, which is annoying,” he said.
I hate those frackin’ stickers on fruit.
