Skin that resembles human skin, and moreover living, is what researchers from the University of Tokyo have created. In a study published in the journal, they present a robot finger covered with an organic skin that has features and healing. A progress that may seem smaller, but which brings us significantly closer ! “I believe that living skin is the ultimate solution to make robots look and feel like living beings because they are exactly the same which covers the body of the animals “said Shoji Takeuchi, first author of the study.
Genuine components of human skin
To get thisthe researchers used a collection of living cells made in vitro and of . A mix inspired by biological substances used in medicine to treat severe wounds and burns. They first immersed the robot finger in a mixture of human skin and collagen to reproduce what is equivalent then covered it all with human epidermis to .
It all then shrank over timewhich surrounds the finger and forms folds that resemble those of real skin. “The advantage of our method of covering 3D objects with what corresponds to skin is the use of tissue shrinkage during cultivation, which allows conformal coverage of 3D objects, especially those with curved and uneven surfaces.” write the researchers.
To check the outfit andof the skin had the team so more to and have more “evaluated the barrier function of manufactured skin equivalents with electrical measurements and testing of », as the researchers write. And it all held up really well! ‘Fingers already’ slightly “wet” straight out of the growth mediumexcited S.Takeuchi. Since the finger is powered by an electric motor, it is also interesting to hear the click of the motor in harmony with a finger that looks like a real one. »
In addition to its aesthetic and mechanical properties, the brand new skin has created properties of. The researchers placed a collagen bandage after having ” hurt ” the robot 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 demonstrate the utility of robots covered with living materials for 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: for the future the team plans to add of hairy, and . “We’re surprised at how good the drug is adapts to the surface of the robotsays Takeuchi. But this work is only the first step towards creating robots covered in living skin. »
