A team of scientists managed to achieve a quantum leap that allowed them to turn radio signals into energy. This discovery will provide the opportunity for phones and other devices to operate without a battery, as well as opening up new ways to use smart technologies. Scientists in the United States have managed to develop a device called Rectina, a semiconductor of a few atoms. Through the device, the Wi-Fi signals captured by a sensor integrated into the device are converted into a constant current suitable for electronic circuits.
The device can be used to power, without the need for a battery for smartphones and laptops, medical devices and wearable technologies, according to a team led by American scientists.
"This new device has important implications for the future of electronic intelligence," the scientists said. "What if we were able to develop electronic systems that could shut down a bridge or cover an entire highway, or the walls of our offices, and emit all electronic information," said Professor Thomas Palacios, director of the Mini Systems Technology Technology Systems Center of the Massachusetts Institute of Technology. About Us? And how can energy be supplied to these electronics? "According to the British newspaper The Independent.
"We have been able to invent a new way to power future electronics by extracting Wi-Fi energy in a way that can easily be integrated into large areas to convey intelligence to everything around us."
During the experiments, Rectena was able to generate about 40 megawatts of power when exposed to normal Wi-Fi signals of about 150 megawatts. This is an energy level that is sufficient to increase the illumination of a simple mobile display or stimulate silicon chips. The research was published in the latest issue of the journal Nature.
For his part, said Spanish professor Jesus Gargalal of the Technical University of Madrid, who participated in the research, that one of the basic applications may come in the field of bones and "disks" that provide health data after eating patients.
