Scientists have developed a new type of artificial skin: bruises are the same as real

Scientists believe that artificial skin equipped with electronic devices and different types of sensors can improve the performance of robots and prostheses, thereby making their behavior closer to humans.

The researchers in this new study took a slightly different route from most studies. They tried to use ion-conducting materials as their technology, rather than conductors that are always compatible with the human body. .

This led to the development of their so-called ionic organic hydrogel. It is understood that it is loaded with a molecule called spiropyran, which changes from light yellow to light purple when subjected to mechanical pressure- -This is a bit like human skin. This forms the basis of what the research team calls I-skin, which is glued to different parts of the volunteer’s body-including fingers, hands and knees-and tested.

Through these experiments, scientists have proved that their I-skin can be bent and stretched without “bruising”, but this will affect the electrical signal. However, repeated pressing, beating, and squeezing did change its color, among which the purple can be maintained for two to five hours, after which I-skin will return to its original color.

Although the current research is still in its infancy, this research provides an interesting example of how artificial skin or similar materials can be applied to the surface of prostheses, robots and even wearable devices and reveal it When did mechanical damage of concern occur.
