[The Epoch Times, June 13, 2022](The Epoch Times reporter Zhang Ni compiled and reported) After six years of research, Italian scientists have invented aartificial skinmore sensitive than human skin, evenmicroorganismSmall objects can be felt.
Anna Maria Coclite of Graz Technical University in Austria presented a “three-in-one” function developed by her research group.artificial skincan sense temperature, humidity, and touch.
This material distributes up to 2,000 particles per square millimetersensor.Inside each sensor ishydrogel polymercoated with a layer of piezoelectric zinc oxide material.
“The hydrogel is absorbent and swells under changes in humidity and temperature,” Cocklett said. “The pressure from the swelling is transmitted to the piezoelectric material outside, which responds in the form of an electrical signal.”
The material they made was only 6 microns thick, or 0.006 millimeters. The thickness of the human epidermis is regarding 0.03 to 2 mm. They might also make the material thinner, Cocklett said.
The smallest object that human skin can feel is regarding 1 square millimeter, and the touch of this smart skin is a thousand times that of human skin.microorganismSmall objects can be felt.
Cocklett said the material might be used in robotics,artificial intelligenceThere will be important uses on the device.
The research was published May 11 in the journal Advanced Materials Technologies. ◇
