3D printing technology is one of the most important technologies of recent years. Even this technology to produce artificial organs It even has the potential to be used.

Now researchers from the University of Bristol in England are working with three-dimensional printers. fingertip that feels like human skin reports their development. According to the findings of the research, published in the journal Royal Society Interface in the form of two articles, this invention is part of machines. like a human Perhaps a solution can be offered to the problem of misunderstanding.

Artificial leather similar to human skin developed with 3D printers

Machines, unlike humans, don’t have tactile fingertips, so their items are something a human owns. useful they cannot understand. However, this roughness has been corrected by researchers at the University of Bristol using a network of needle-like projections that mimic the ‘dermal papilla’ on our skin, which can also form our fingerprints. sense of touch can disappear through their re-creation.

Professor Nathan Lepora, of the Department of Applied Mathematics at the University of Bristol, said his work helped reveal how the complex internal structure of human skin creates our human sense of touch. “This is an exciting development in soft robotics – being able to 3D print tactile skin can create more agile robots or give them a built-in tactile feel. significantly improve the performance of prosthetic hands. may increase” saves as.

However, Lepora has proven that the artificial nerve recordings in the fingertips made with a 3D printer were made more than 40 years ago. very similar to real records. and he states that it is extremely exciting. Lepora states that the real records are very complex with the hills and slopes on the edges and ridges, noting that the same shapes are present in the artificial tactile data.

The artificial nerves in the artificial fingertips are very similar to the real nerve endings recordings.

The researchers state that there is a very close resemblance between the artificial fingertip and the nerve signals received in humans, but the researchers still say that the artificial fingertip is so sensitive to fine details. not sensitive there stands that. The reason for this may be that the skin made with the 3D printer is thicker than the skin of adult humans; but the same technology in the future on a microscopic scale It is argued that this problem can be eliminated with the development of printing in a way that prints.

On the other hand, Lepora strives to make both artificial leather and real leather, even much better He adds that it is to make
