Material created by scientists University of TokyoNot like Human skin Not only in its structure, when a person sweats, water also comes out of it and it can heal itself from wounds by “plasters”. Collagen.

In order to clarify how this skin works, an article published in the magazine revealed ThingThe idea is based on “soaking the robot’s finger in a solution of collagen and human skin fibroblasts (the two main components that make up connective tissue in human skin).”.

Collagen contributes to the elasticity and strength of the skin, while fibroblasts play an important role in hair growth and wound healing..

“I think the ultimate solution for giving robots the look and feel of living things is live skin because it’s the same material that makes up animals,” said Shuji Taguchi, the study’s lead author.

He also expressed his admiration: “Since the finger is powered by an electric motor, it is interesting to hear the clicking sounds of the motor, identical with the finger that looks like a real finger.”.

Scientists believe that robots, especially those used in health care, are “important” to be as close to humans as possible because many of them are intended to interact with people working in the health and services services, if they feel comfortable. They interact with people like them.

Are done Synthetic leather From current SiliconIt mimics human appearance, but does not work well enough when it comes to fine details like wrinkles.

Dermatological functions such as silicone cannot be performed Sweat Or “cure itself”, and can not be easily installed on dynamic objects with uneven surfaces such as robots.

Tagucci and his team covered the skin with keratinocytes found in the epidermis that make up 90 percent of the outer layer of the skin. Human skin.

“We were amazed at how well the skin tissue fits on the surface of the robot, but this work is the first step in creating robots covered with live skin,” he said.

More growth is needed to increase strength Synthetic leatherHelps to survive longer without providing nutrients and removing waste.

The team of scientists is looking to integrate more complex functional structures into the skin, such as sensory neurons, hair follicles, nails and sweat glands..
