Looks ta cat’s tongue and you’ll notice that it’s rough with a sandpaper-like texture. The tiny claw-shaped hooks on a cat’s tongue helps it groom itself. When a cat licks itself, built-in scoops on these hooks carry saliva to the skin to cool it down.
“Their tongue could help us apply fluids, or clean carpets, or apply medicine” to hairy skin, said Georgia Institute of Technology lead researcher Alexis Noel, who is seeking a patent for a 3D-printed, tongue-inspired brush.
Of course, cats should really be awarded this patent since it’s their tongues that inspired this patent in the first place. To read more about the science behind a cat’s tongue, click here.
