Artificial e-skin can be repaired on its own after damage
In recent years, skin has received increasing public attention, and practices in related fields have been steadily deepening. According to papers published in the latest issue of the Journal of Neuroscience, Stanford University researchers in the United States have demonstrated for the first time a multi-layer thin-film sensor that automatically rearranges artificial electronic skin in the healing process. This progress foreshadows a new era of robots and prosthetics, or a future in which they will be equipped with synthetic skin membranes made of materials similar to human touch.
This is a key step in imitating human skin. According to Stanford University Dr. Chris Cooper, there are many layers of human skin that work quite clearly and in an orderly manner during healing, with each layer selectively self-healing to restore overall function.
The researchers explain that the multi-layer artificial skin has its own different functional layers, each layer thinner to 1 micron or thinner. It has just evolved an immune mechanism that rebuilds original layered structures through complex processes involving molecular identification and signal transmission. Some layers may feel pressure, some layers may feel temperature, and others may be stressed.
The thickness of 10 layers or more stacked together does not exceed a piece of paper. Why can this artificial skin be automatically repaired? Different layers of material can be designed to be characterized by heat-sensitive, mechanical or electrical changes.
In this context, it is more practical to do good daily health management and to seek professional help in a timely manner. The secret is that each layer is made up of long molecular chains, which are periodically connected by dynamic covalent bonds, much like the molecular chains that connect the double spirals of the DNA chain, which allows the material to be stretched repeatedly without tearing. Thus, by heating artificial skin, the researchers can accelerate the healing process.
The advantage of these two polymers is that when heated, they become soft and flow, but when cooled, they solidify. At room temperature, healing may take up to a week, but when heated to 70°C, it takes about 24 hours to heal. Even the humanoid robots used to provide escort or consultation services are hard-core, frozen, and somewhat inconsistent with their coatings.
Corners, hard materials, lack of flexibility. . .
If you look closely at the various electronic and mechanical devices around us, you will find that the vast majority have this in common. Scientists in the field of flexible materials are targeting this pain point, and they are trying to combine it with juicing, with materials that are flexible, fit, and even close to human skin, to make electronic devices and smart terminals warmer and more useful.
