The researchers designed wireless energy transmissions that can be recharged to cell phones or laptops without the need for new devices using cables. Researchers at the University of Technology (UPV) in Spain have invented a system based on radial photonic crystal resonators; one of them will act as an energy transmitter and other charging device that will need to be set up. . Between them is called the resonant coupling phenomenon, which is the last device to generate charge or recharge.
“This phenomenon produces a resonant object that moves closer to the second resonant element and the two resonant frequencies are the same or very similar,†said Jose Sanchez de Esa, a researcher at the University of Technology in Valencia. "Such physical proximity results from the first device acting as a source to the second, acting as an energy coupling for the charge," said Sanchez de Esa.
The device can also be used as a power system device such as a keyboard and wireless mouse, a speaker, and the like. In addition to consumer electronics, it can also be used in the industrial environment, as the power source of robots or vans, and the first prototype of electrophysiological devices (pacemakers, defibrillators, etc.) are being developed, the researchers said. .
