Smart Bionic Finger 3D Scan Poke
Lay’s Finger Cleaner may be slightly more interesting, but this smart bionic finger developed by researchers at Wiyu University (WYU) can do so much more. Put simply, this smart bionic finger can produce 3D maps of the internal shapes and textures of complex objects by poking their exterior surface.



After poking the object, the smart bionic finger then analyzes its contraction as well as the material touched to produce the 3D scan. In addition to just the surface, nearly all of the structures beneath the surface are also rendered in three-dimensions. One of the tests involved it scanning a rigid “letter A” covered in a layer of soft silicon, while another had it sensing and imaging synthetic human tissue.

This tactile technology opens up a non-optical way for the nondestructive testing of the human body and flexible electronics. Next, we want to develop the bionic finger’s capacity for omnidirectional detection with different surface materials. Our bionic finger goes beyond previous artificial sensors that were only capable of recognizing and discriminating between external shapes, surface textures, and hardness,” said Zhiming Chen, co-author a lecturer at Wuyi University.
