Recently, researchers from the Fraunhofer Institute in Germany have developed a new type of fiber that can detect the intrusion of thieves. According to the researchers, the outer layer of the fiber is coated with a layer of silver, which is then integrated into a mesh and finally connected to a microcontroller. Once it is detected that someone has destroyed the weak current generated by the web, the controller will send a warning message to the house owner.
In addition to the above-mentioned feature, this smart fiber will also be able to ensure the safety of the user's road car inspection or banking, jewelry stores and museums.
According to researchers at the Fraunhofer Institute, the cost of this smart fiber is relatively low compared to other materials. Moreover, it can also be reduced to any size.
HCs, also called Natural refrigerants are chemicals which occur in nature's bio-chemical processes. They do not deplete the ozone layer and make a negligible - or zero in the case of HC-22 and HC-134A - contribution to global warming. The high efficiency of natural refrigerants also means that they make a lower indirect contribution to global warming.
These products were used as refrigerants
prior to the 1950s, before fluorocarbon refrigerants became commonplace. They
are now being used more extensively due to their low impact on the
environment.
