Mechanism design of elements for artificial tongue taking triangle element division imitated arrangement of Lingual muscle

In this research, we developed an element of mechanical speech synthesizer to study how human speech works. Following a concept of biomimetics, artificial tongue constitutes elements taking finite triangle elements which imitated arrangement of a human lingual muscle. And each element transforms under constant volume, because some branches of that triangle shrink actively, some, the branches become longer passively. These triangular elements are located in the shapes of a mesh, and form lingual shape. At first, we consider a mechanism which can transform a few elements with experimentation and simulation
