Rebuilt after the war in record time, Japanese industry has always relied on tecnologic innovation to overcome adversity.
The land of the rising sun has a decades-long relationship with innovation. Since its rebirth after the Second World War, Japan has a blueprint for the future in technology.
Initiated in the 1950s and strongly based on the country's industrialization, the post-conflict recovery plan relied on large investments in Japanese companies and, above all, in the qualification of their citizens.
The field of robotics is one of the most outstanding in Japan, it is no coincidence that the country is the number one reference in the world when it comes to robotics.
Robot with 'human skin' created in Japan
A robotic finger covered in fur artificial fabric grown from living cells was successfully developed by a group of scientists led by Shoji Takeuchi, professor of machine engineering at the University of Tokyo.
Skin can be regenerated if damaged. This will likely lead to the development of robots whose skin is similar in texture to humans.
The robot finger is about 1cm in diameter and 5cm in length. Its surface is covered with cultured human skin cells.
Scientists developed the culture method to produce two different parts that make up the skin: the epidermis for the surface and the dermis under it.
The cultivated skin is 1,5 mm thick. It is strong enough not to break even if the finger is bent or stretched at any of its three knuckles. If the surface is cut or damaged, the skin can repair itself by having a sheet of collagen glued to it and being immersed in a cultured solution.
The skin is not intended for long-term use because it lacks blood vessels to provide nourishment.
“We would like to improve it by adding nerves and blood vessels in the future,” said Takeuchi.
