Terminator soon a reality with this first “living” robot skin?

Skin resembling human skin, and moreover alive, is what scientists from the University of Tokyo have created. In a study published in the journal matter, they present a robotic finger covered with an organic skin, possessing functions Water repellent treatments

This is a treatment that is applied to the surface of the walls…” data-image=” /2b7c6023f3_50037415_2371202428-880831b8f6-02.jpg” data-url=”” data-more=”Read more”>water repellent and healing. An advance which may seem minor but which brings us significantly closer to real humanoids ! “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…

said Shoji Takeuchi, first author of the study.

Genuine components of human skin

To get this texturethe researchers used an assembly of living cells made in vitro and of collagen. A blend inspired by implants biologicals used in medicine to treat serious wounds and burns. They first immersed the robotic finger in a mixture of Fibroblasts are present in the dermis where they produce extracellular matrix components such as…” data-image=”https://cdn.futura-sciences. com/buildsv6/images/midioriginal/6/5/0/650c398bdd_113991_fibroblast-cell.jpg” data-url=”” data-more= “Read more”>fibroblasts human skin and collagen to reproduce the equivalent of dermisthen covered the whole thing with Structure of keratinocytes

The whole thing then shrunk during the Reverse phase change is called “melting”.

And it all held up really well! ‘The finger al’air 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. »

Healing properties

In addition to its aesthetic and mechanical characteristics, the brand new skin created has properties ofself healing. 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 nutrient supply : for the future, the team plans to add sensory neuronsof the follicles hairy, nails and eccrine sweat glands

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