Scientists from the University of Manchester (UK) have made new strides in the development of adaptive "smart" tissue, which is based on graphene. Scientists decided to use its property to change its parameter of infrared radiation conductivity when a small electric current is applied. In the course of research, they managed to create a tissue that can be switched between two states - for blocking IF radiation and its free transmission.
Initially, it was about thermal masking, when with the help of a blocking tissue it would be possible to keep the infrared radiation of the human body inside the shell. And thus make it invisible to thermal imagers. But the accumulated heat needs to be removed somewhere - this is how the idea arose to transform the disguise into a new type of cooling and warming clothing.
The pictures show a prototype of "smart textiles", from which a fragment was made on the chest part of a T-shirt. It switches between two modes, in one of which it provides free passage of infrared radiation and removal of heat from the body, and in the other it blocks it. And, accordingly, it warms or cools the body of its owner.
But clothing is only one aspect of the application of this technology. Scientists want to develop on its basis a dynamic coverage for satellites that are forced to constantly move from space cold in the shadow of the Earth to an unprecedented heat when illuminated by the Sun, and so on, cycle after cycle. For onboard equipment, these are very difficult conditions, so quickly adaptable thermal protection is in great demand here.
