I'm reading: 3D synthetic tongue

3D synthetic tongue

Despite the challenges of a complex architecture, researchers have created a synthetic soft surface replica of the human tongue that mimics its topography and wettability – factors that influence how food and saliva interact upon its surface. Researchers used tongue masks obtained from healthy human subjects and digital light processing technology to make a 3D printed tongue mould. This silicone-based tongue surface could help accelerate the development of nutritional, biomedical and clinical products. It is a result of an interdisciplinary collaboration with the University of Edinburgh, which was led by Anwesha Sarkar, Professor of Colloids and Surfaces.
