Appearance of the fingertip
The papillae are made using a state-of-the-art 3D printer, and the device can combine soft and hard materials to create complex, biological-like structures.
Our work helps to understand how complexThe internal structure of human skin helps us sense touch. The development will help advance research in the field of 3D printing of tactile skin. In the future, there will be robots that will become more dexterous, as well as new comfortable prosthetics.

The authors discovered that our fingertip,3D printed can generate artificial nerve signals that are similar to the activity of real receptors. Human receptors transmit signals from various nerve endings.
When they tested the artificial fingertip, Lepore said, they found a striking match with the original human signals.
