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
You can use a water repellent treatment to fight water intrusion that creates moisture and stains. This treatment is applied to the surface of the walls … “data-image =” https://cdn.futura-sciences.com/buildsv6/images/midoriginal/2/b/7/2b7c6023f3_50037415_2371202428-880831b8f6-02.jpg”data- url =” https://news.google.com/house/definitions/waterproof-house-10720/ “data-more =” read more “> 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 things, because they are exactly the same building materials, smart materials, environmentally friendly materials…

Then everything shrinks during a reverse phase change called “melting”.

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. »
In addition to its aesthetic and mechanical properties, the new skin created has properties. The researchers applied a collagen bandage after eating them ” 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 concluded that developed skin remains weaker than normal skin, and requires that
