Skin that looks like human skin, and is even more alive, is what scientists from the University of Tokyo have created. In a study published in the journal And the They present a robotic finger covered with organic skin, which has functions and healing. Progress may seem small, but it brings us remarkably close ! “I think live skin is the ultimate solution to making robots look like living beings, because they are exactly the same that covers the body of animalsShuji Takeuchi, the study’s first author said.

Then everything shrunk throughsurrounds the finger and forms folds similar to those of real leather. “The advantage of our method for covering 3D objects in the equivalent of the skin is the use of tissue shrinkage during culture, which allows identical coverage of 3D objects, especially those with curved and uneven surfaces.” , Write researchers.
To check the outfit andand has more “Assessing the barrier function of synthetic skin equivalents.” With electrical measurements and tests “,” As the researchers write. And it all held up really well! “the finger” Slightly “moisten” directly from the growing mediumS.Takeuchi, excited. Since the finger is powered by an electric motor, it is also interesting to hear the motor clicks in unison with a finger that looks like a real finger. »From the leather, the team had several to me
In addition to its aesthetic and mechanical properties, the new skin created has properties. The researchers put a collagen bandage after eating it ” injury ” The robotic finger: the bandage gradually dissolves in the skin and thus rebuilds it! “The wound was repaired by the activity of dermal fibroblasts after the collagen layer was applied to the wound site. These results demonstrate the applicability of robots encased in living materials to biological functions and provide a new perspective on robotic materials.”
But this is only the beginning, as the study concludes that developed skin remains weaker than normal skin, and requires that : For the future, the team plans to add subordinate hairy and the . “We are amazed at the quality of the fabric Compatible with the surface of the robotsays Takeuchi. But this work is only the first step towards creating robots covered with live skin. »
