Scientists covered a robot finger in living human skin

Robots can now be covered in living skin grown from real human cells to make them look more like us.

As robots increasingly take on roles as nurses, care workers, teachers and other jobs that involve close personal contact, it is important to make them look more human so we feel comfortable interacting with them, says Shoji Takeuchi at the University of Tokyo in Japan.

At the moment, robots are sometimes coated in silicone rubber to give them a fleshy appearance, but the rubber lacks the texture of human skin, he says.

To make more realistic-looking skin, Takeuchi and his colleagues bathed a plastic robot finger in a soup of collagen and human skin cells called fibroblasts for three days. The collagen and fibroblasts adhered to the finger and formed a layer similar to the dermis, which is the second-from-top layer of human skin.

Next, they gently poured other human skin cells called keratinocytes onto the finger to recreate the upper layer of human skin, called the epidermis.

The resulting 1.5-millimetre-thick skin was able to stretch and contract as the finger bent backwards and forwards. As it did this, it wrinkled like normal skin, says Takeuchi. “It is much more realistic than silicone.”

Scientists in Japan have created a robotic finger coated in living skin, in what they say could be a major step towards creating robots with a genuine human likeness. Like real human skin, the lab-grown coating is water-repellent, wrinkles up when the robot's finger curls and even has the ability to heal itself.

This is just amazing. I wounder who is more advanced in robotic technology....the US or Japan. It seems like Japan is coming out with amazing robotic news ever week.

I guess this is one step closer to creating the first terminator haha. But seriously... how much longer do you think it'll be before the first one is created?
