A multidisciplinary team has 3D printed an exact copy of the human tongue, complete with artificial smooth surfaces and tongue-like tissues.

The scientists led by the University of Leeds, in collaboration with the University of Edinburgh, By accurately simulating the surface of the human tongue, which plays an important role in how food tastes, the way food is spoken and swallowed, and nutrient absorption, among other functions.

Scientists claim that biomimetic tongue accurately mimics the structure Flexibility and “wettability.”

The structure of a synthetic silicone can play a game-changer role in examining new oral technologies, while improving nutritional technologies, medicines and treatments for dry mouth. According to Russia Today.

The team, consisting of food scientists and experts in soft matter physics, dentistry, mechanical engineering as well as computer science, focused on the anterior dorsal part (roughly the middle of the visible tongue, after The tip but before the base.)

This region is partially covered by some papillae (small gaps spread across the tongue), which contain taste receptors, although not all of them act as taste receptors. The team took molds for tongue roofs from 15 adult participants.

Lead author, Dr. Evrin Andablo Reyes, who described the work as a “unique architectural challenge,” said: “Hundreds of small structures that resemble The buds, which are called papillae, give the tongue a distinctive rough texture, which, along with the smooth nature of the tissues, creates a complex landscape from a mechanical perspective.

These impressions were then visually scanned with a technique. 3D mapping of the dimensions of papillae on the surface, as well as their density and average overall roughness of human tongues. It turns out that the texture is very similar to the random layout.
