Electronic skin future is here

The new electronic skin remains unchanged even after being stretched up to 28 times compared to the original size …

The material, which completely imitates human skin, is strong and stretchy enough, but at the same time sensitive, and could be used to collect biological data in real time. Electronic skin (e-skin) could get a very important role in prosthetics, then personalized medicine, the so-called. soft robotics, as in the field of artificial intelligence.

This material is the work of scientists from the Saudi University of Science and Technology, King Abdullah (KAUST), who claim that e-skin is able to mimic the functions of human skin, such as the feeling of touch and heat, ie cold.

It differs from similar materials in that it contains 2D sensors, which, although made of mechanically strong materials, are very thin, which enables e-skin functionality and durability. Realistic e-skin is made of hydrogel reinforced with nanoparticles of silicon dioxide and 2D titanium carbide, all connected by nanowires.

The e-skin remains unchanged even after being stretched up to 28 times the original size. It is able to “feel” objects at a distance of 20 centimeters, to respond to stimuli in less than one tenth, and when used as a pressure sensor, it could detect writing with a pencil on it.
