Skin resembling human skin, and moreover alive, is what scientists from the University of Tokyo have created. In a study published in the journal

An advance which may seem minor but which brings us significantly closer to ! “I think living skin is the ultimate solution to make robots look and feel like living creatures, because it’s exactly the same Building Materials, Smart Materials, Eco-Friendly Materials…

Genuine components of human skin

To check the hold and The body is perfectly elastic if it completely recovers its original shape after removing the load.
It is partially elastic if the deformation produced by the forces…” data-url=”https://news.google.com/sciences/definitions/physics-elasticity-2077/” data-more=”Read more” > of the skin, the team then had several to and has more “evaluated the barrier function of fabricated skin equivalents with electrical measurements and tests of », as the researchers write. And it all held up really well! ‘The finger al’ slightly “wet” straight out of the growing mediumenthused S.Takeuchi. As the finger is driven by an electric motor, it is also interesting to hear the clicks of the motor in harmony with a finger that looks like a real one. »
In addition to its aesthetic and mechanical characteristics, the brand new skin created has properties of. The researchers placed a collagen bandage after having ” hurt ” the robotic finger: the bandage gradually melted into the skin and thus rebuilt it! “The wound was repaired by dermal fibroblast activity after the collagen sheet was applied to the wound site. These results show the applicability of robots covered with living materials to biological functions and offer a new perspective on robotic materials. »
But this is only the beginning, as the study concludes: developed skin remains weaker than natural skin, and requires

But this work is only the first step towards creating robots covered in living skin. »
