Researchers at the Massachusetts Institute of Technology have developed a method for collecting radio energy, in order to charge graphene batteries. It is noteworthy that the role of such a “generator” is capable of performing a conventional Wi-Fi router; and for “refueling”; the gadget doesn’t need a cable, it’s enough to be in the coverage area of the wireless network.
The proposed method is based on the use of terahertz electromagnetic waves; with a frequency in the range between microwave and infrared radiation. The so-called T-rays come from almost all objects having a temperature, including the human body. After analyzing the nature of radiation, scientists concluded that it can be used as an alternative energy source. All that is needed to recharge various gadgets, is a special concentrator capable of “collecting” these waves with further conversion into electric current.
Researchers at the university managed to force the electrons of the material, to move in a certain direction, and after that convert them into a charge. By means of a graphene to concentrate radiation. It has a symmetrical molecular lattice and is devoid of impurities; which allows you to effectively convert T-rays into current when using a special layer of boron nitride; which changes the direction of the flow of electrons and leads to the appearance of a charge.
At present, physicists are developing a prototype capable of operating outside the laboratory. In the future, according to the creators of the new technology, devices based on it will be able to supplement solar panels and other “green” energy sources.
