Americans developed the electronic skin, and the Japanese brought out the material repeating the structure of human muscles
The XXI century will surely be remembered as the period in which modern technologies were used to design not only innovative electric gadgets, but also for developments in the field of genetic engineering.
The latest news on this topic came from America and Japan. In the first case, scientists managed to create an artificial electronic skin, in the second – a material that is not inferior to the heart in terms of wear resistance.
How does the electronic skin work and what can it do?
The electronic skin, according to scientists from universities in the US state of Connecticut and the Canadian city of Toronto, will be able to provide their “carrier” with supernormal abilities. Sensors that respond to pressure drops and changes in magnetic fields are responsible for this.
The development was created on the basis of a difficult-to-understand multimodal nanogenerator technology, consisting of an elastic silicone tube, inside which there is ferrofluid. It is also known as ferromagnetic fluid, whose polarity is enhanced greatly by a magnetic field. The same tube is wrapped with copper wires to transmit electrical signals. The high level of water resistance and the ability to stretch also allow the skin to stay in shape for years.
So far, the development is waiting to obtain the necessary licenses and permits so that it can be used in search operations after emergencies, as well as to create prostheses for people affected by severe burns.
Artificial muscles from the Japanese: what are they is and where can they be applied?
In attempts to expand the horizons of the possibilities of technology, scientists have been puzzling for more than a year about creating a material that in terms of durability would not be inferior to human muscles. After all, it is not difficult to imagine what will happen to the robot if he goes to the gym to work out – the metal or plastic construction will fall apart after a couple of lessons.
It seems that Japanese scientists managed to make a big step in this direction. Specialists from Hokkaido University, led by Professor Jianping Gong, created a structure that, by its characteristics, can be as powerful as the tissue of the heart. Recall that the main organ of a human is able to give out 72 beats per minute for more than one century.
The basis for the Japanese material has become a hydrogel of rigid and elastic components. The 85% development consists of liquids in which the monomers are dissolved, and they, in turn, form molecules. Just like amino acids in human living tissues.
Jianping Gong believes that his joint discovery with his colleagues will become a springboard to the creation of even more flexible and durable materials, which in the future will serve, as the basis for exoskeletons and, in theory, will even be used in muscle regeneration.
