a chilling robotic finger Made with a solution composed of collagen and human dermal fibroblast cells, it was created by scientists at the University of Tokyo, with the aim of manufacturing more realistic prostheses in the future.
Not only is the coat water-repellent, but scientists say it can also heal itself and even retain moisture.
“We are surprised by how well the skin tissue conforms to the robot’s surface,” said Shoji Takeuchi, a professor at the University of Tokyo and lead author of a study. new item published in the magazine Matterin a statement. “But this work is only the first step toward creating robots covered in living skin.”
When the robotic device was later tested, it was found that the skin was strong and elastic enough to bend and stretch along with the finger, without breaking. Furthermore, when the skin was cut and then covered with a collagen bandage, that bandage proceeded to gradually transform into the surrounding skin, thus healing the wound.
“The finger looks slightly ‘sweaty’ straight from the cultural milieu,” first author Shoji Takeuchi, also a professor at the University of Tokyo, said in the statement. “Since the finger is powered by an electric motor, it’s also interesting to hear the clicking sounds of the motor in harmony with a finger that looks like a real one.”
“I believe that living skin is the ultimate solution to give robots the look and feel of living creatures, as it is the exact same material that covers animal bodies,” Takeuchi concluded.
