This robot finger heals human cell skin.,Shoji Takeuchi constructed a robot finger with live skin derived from human cells. As a result, Takeuchi’s finger can bend and curl without breaking, and if it develops a cut, it can mend and reseal itself.

Takeuchi explained that silicone rubber coverings typically used in robots might seem authentic from a distance or in images or movies, but up close, they are fake. We believe the only way to attain a human-like look is to use live cells.
The live skin, described in Matter, was formed by immersing a robotic finger in a solution comprising collagen and human dermal fibroblasts. As collagen and fibroblasts tightened around the artificial appendage, Takeuchi felt the hyper-realistic finger was a success.

Once the collagen-fibroblast foundation was created, human epidermal keratinocytes adhered to it, forming 90% of the human skin’s outermost layer. This gives the robot-human combination a more lifelike feel even if it seems “slightly sweaty out of the culture medium,” Takeuchi added.

Keratinocytes make human skin waterproof and the robot finger waterproof, which is vital for aesthetics and function. Living skin can regenerate itself if harmed yet is robust enough to withstand bending, curling, and tweezing.
The researchers applied collagen to the robotic finger’s wound and left it for seven days. During this period, skin cells might migrate into the collagen patch and integrate it into the skin, closing the wound.

Living skin has drawbacks for humans, as anybody with adolescent acne knows. Could robots be susceptible to germs or infections?

Takeuchi told IFLScience, “The more human-like the skin, the more likely it is.” Changing cells might develop resistant tissue.

Complex living skin (and the capacity to feel pain) might be on the cards for robots.

Takeuchi said there’s no vascular system in the skin, so it doesn’t stay long when removed from the culture media.

“We’re developing skin circulation systems.” Another issue is reproducing organs such as sensory neurons, hair follicles, nails, and sweat glands in the skin. Also, expanding our existing technology to larger structures would be difficult.
