A team of scientists managed to make a leap forward that allowed them to turn radio signals into energy. This discovery will allow phones and other devices to run without batteries, while opening up new ways to use smart technologies. In the United States, scientists have developed a device called Rectina, a semiconductor of a few atoms. Through the device, Wi-Fi signals captured by a sensor built into the device are converted into a constant current suitable for electronic circuits.
According to a team led by US scientists, the device can be used to provide power without the need for a battery for smartphones and laptops, medical devices and portable technologies.
"This new device has major implications for the future of electronic intelligence," the scientists said. "And if we managed to develop electronic systems that could close a bridge or cover an entire highway, or the walls of our offices, while emitting all the electronic information," said Professor Thomas Palacios, director of the Mini-System of Massachusetts Institute of Technology technology systems. About us And how to supply energy to these electronic devices? ", According to the British newspaper" The Independent ".
"We have succeeded in inventing a new way of powering future electronic energy devices by extracting Wi-Fi energy so that it can be easily integrated into large areas, in order to transmit information to everything around us. "
During the experiments, Rectena managed to generate about 40 megawatts of power when it was exposed to normal Wi-Fi signals of about 150 megawatts. This is a sufficient level of energy to increase the illumination of a simple mobile screen or to stimulate silicon chips. The research was published in the latest issue of the journal Nature.
For its part, said Spanish professor Jesus Gargalal, of the Technical University of Madrid, who participated in the research, one of the fundamental applications can come from the field of bones and "disks" that provide health data after swallowing patients.
