If you also don’t like to change outfits according to seasons, a new advancement in science has mouthwatering news for you. Material scientists and engineers at Stanford University have received success in a project.
They have successfully developed a multilayered textile material that has the capability or characteristic to trap body heat on one side and when it is flipped the other way round, it can passively radiate body heat away.
The material, when tested, had the capability to keep artificial skin within a comfortable range of temperature. The artificial skin could be maintained between Thirty-two and Thirty-six-degree centigrade as the temperature of the ambience experienced a fluctuation of Nine-degree centigrade during the period of conduction test.
As far as the observed looks of the textile are concerned, it looks like a gnarly sandwich. Layers of Nano-porous polythene or Nano-PE were in contact with two more layers. One was a rough porous layer of carbon and the other was a smoother and tighter layer of copper.
Now, the textile was classified to act on two modes according to the layers near and away from the body. To explain it in a simple manner, the textile would be in cooling mode or wood cool the body when the layer of carbon faces away from the body and the thin Nano-polythene or Nano-PE layer is facing towards the body(near the skin).
It is to be noted here that the reason behind this is the body heat can be easily lost through a carbon structure which was clearly observed in the experiments. In the experiments, the temperature of the artificial skin could be lowered as much as three degrees.
To warm up the body, the fabric is reversed to let the copper layer face out. The copper layer, here, acts as the insulator and doesn’t let the body heat escape.
