Terminator movie soon a reality with the skin of a ‘live’ robot?

Skin that looks like human skin, and is more vibrant, is what scientists at the University of Tokyo have created. In a study published in the journal issueand the They present a robotic finger covered with organic skin, which has functions Water Resistant and healing. The progress may seem small, but it brings us remarkably close real people“I think live skin is the ultimate solution to making robots look like living beings, because they are exactly the same Material that covers the body of animalsShuji Takeuchi, the study’s lead author said.

Original ingredients for human skin

to get this textureThe researchers used an array of living cells made in the laboratory Based on collagen† A blend inspired by the plants Biological substances used in medicine to treat severe wounds and burns. They first immerse the robot’s finger in a mixture of fibrous Human skin and collagen are equivalent to reproduction dermisThen it covered everything keratinocytes human skin Create a complexion

Then everything shrunk hardeningIt surrounds the finger and forms folds similar to those of normal skin. “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 searches.

To check the outfit andFlexibility From the leather, the team had several movements to me automated fingerAnd she has more “Assessment of barrier function for the equivalent of artificial skin.” in the laboratory With electrical measurements and tests WaterproofAs the researchers write. Everything has held up very well! “finger”sky Slightly “moisten” directly from the growth mediumS. Takeuchi, excited. Since the finger is powered by an electric motor, it is also interesting to hear the motor clicking in unison with a finger that looks like a real finger. †

healing properties

In addition to aesthetic and mechanical properties, the newly created leather has characteristicsself healing† Researchers made a collagen pad after eating it “infection” Robot Finger: The pad gradually dissolves into the skin and rebuilds it in no time! “The wound was repaired by the activity of dermal fibroblasts after a layer of collagen was applied to the wound. These results demonstrate the applicability of robots encapsulated in living materials for biological functions and provide a new perspective for robotic materials.”
