Artificial Leather Developed That ‘Feels Like Human Skin’

3D printing technology is in the middle of the most valuable technologies of recent years. In fact, this technology has the potential to be used to produce artificial organs in the future.

Now, researchers from the University of Bristol in England report that they have developed a fingertip that feels exactly like human skin with 3D printers. According to the findings of the research published in the journal Royal Society Interface in the form of two articles, it may be possible that this invention offers an analysis of the problem of machines’ inability to grasp things like a human.

Artificial leather similar to human skin was developed with 3D printers

Unlike humans, machines that do not have tactile fingertips, therefore cannot grasp objects with the dexterity of a human. However, this roughness can be eliminated when researchers from the University of Bristol recreate the sense of touch by using a network of needle-like projections that mimic the ‘dermal papilla’ on our skin, which also enables our fingerprints to form.

Professor Nathan Lepora, from Bristol University’s Department of Engineering Mathematics, said that his work helped to reveal how the complex internal structure of human skin creates our human sense of touch. “This is an exciting development in the field of soft robotics – tactile skin in 3D Being able to print can create more dexterous robots or significantly improve the performance of prosthetic hands by giving them a built-in sense of touch.”

In addition, Lepora says that the artificial border records on the fingertips produced by 3D printers can be compared to real records more than 40 years ago. Lepora states that the real records are very complex with the peaks and slopes on the edges and ridges, and notes that the exact shapes are also present in the artificial tactile information.

Noting that there is a very close match between the artificial fingertip and the border signals received in humans, the researchers said that the artificial fingertip is not that sensitive to fine details. is talking. The reason for this may be that the skin created with the 3D printer is thicker than the skin of adult humans; However, it is stated that in the future, this problem can be eliminated with the development of the same technology in the form of printing on a microscopic scale.

On the other hand, Lepora adds that their main aim is to make artificial leather as affordable as real leather, if not more.
