Technological advances have allowed scientists to create the so-called Electronic skinOr “electronic skin”, which can also become Wear tools from the future. Now, of course, many readers will wonder what this term covers and why the creators of it technology They believe that this prediction will come true.

It is a flexible circuit technology based on the characteristics of human skin and aims to obtain an artificial skin that can replace natural skin without losing tactile ability. It is not an easy task to make the wearer feel comfortable, durable and sensitive at the same time. researchers RMIT University Melbourne, Australia, is said to have made the most significant progress in this area.

“It was in the 1980s that we started to see touch sensors that we could call a crude version of the skin,” he told the international publication Scientific American. Ravinder DahiyaProfessor of Electronics and Nanotechnology, RMIT University.

As you read, this is not the first time something like this has gone wrong. This university has been trying to improve in this direction for years. Human skin is incredibly complex, full of sensitive points and connected to the nervous system so the brain can communicate and receive external sensations. Take this away artificial world This is not an easy task.

How do these electronic skins work?

According to the prototype they developed, it can electronically copy the skin’s reaction to it pain. The verb “react” is important because it does not refer to perception, but to how it works. In other words, it’s relatively easy to get sensors that detect it pressure on or above the surface warmth. However, mimicking responses by detecting pain almost instantaneously, as the brain does, is difficult.

Pain is not something that an artificial device can feel, although it can feel pressure or registration temperature. And ultimately pain is a combination of these two factors. A high enough temperature will cause pain. So, for example, with a “puncture” that applies too much pressure to too little surface area.

Therefore, the researchers installed several sensors plates Very thin (as you can see in the photos in this article) that can measure pressure and temperature.

In previous research, it was possible to flex and stretch the reactive coating at a temperature of only one micrometer from the material, or electronic memory elements for storing information. By combining these techniques, they say they have a working prototype.

Electronic memory cells function differently depending on temperature and recorded pressure. Therefore, it performs this or that function as needed. Or in other words, this electronic skin can know when the needle touches it and when it bends to a level that can damage the surface.

And why they are said to be the wearable technology of the future

It is believed that this is due to the use that can be given to the field Health. Engineers in this regard Mariam Turk, Chuan Li i Lixnaxi Zheng Added to the previously mentioned media that “Electronic skin mimics human sensory capabilities, providing many potential applications in robotics, artificial intelligence, prosthetics and health monitoring technologies.”
