Look at a 3D printed texture that looks like a tongue

British scientists led by the University of Leeds in collaboration with the University of Edinburgh

reproduced complex surface designshuman language. The printed synthetic silicone structure mimics the topology, elasticity and wettability of the tongue surface. These factors play an important role in how food or saliva interacts with the tongue, which can affect mouthfeel, swallowing, speech, and food intake.

The printed language helps developers validate newly developed products and accelerate development processes without the need for early human testing.

In particular, since the onset of the COVID-19 pandemic, social distancing has created major challenges for such sensory testing and consumer testing. An artificial language will also help with this.

Recreating the surface of the averagehuman language is fraught with unique architectural challenges. Hundreds of small kidney-like structures called papillae give the tongue its characteristic rough texture, which, when combined with the soft nature of the tissue, creates a complex landscape.

The team took silicone impressions of the tongue surfaces of fifteen adults. The impressions were optically scanned in 3D to show papillary size, density and average tongue roughness.
