generating electricity from Wi-Fi
Scientists claim to be able to convert Wi-Fi signals into electricity, which could help devices run without batteries in the future.
According to a report by Tasnim news agency, scientists at the Massachusetts Institute of Technology have developed a machine that can convert Wi-Fi signals into electricity. According to the researchers, by converting the Wi-Fi signal into electricity, it will be possible to power the 2D device entirely from Wi-Fi waves and eliminate the need for a battery.
Wi-Fi has become a rapidly expanding power source and the new machine could convert its signal into a useful electrical current, he said. He said the antenna converts alternating current (AC) waves into DC current voltages that can be used in electrical products.
The MIT team claimed that this technology could be used to power electronic products, smart watches, and medical devices. Scientists said that we have found a new way to power the electrical system in the future and it will be possible to use Wi-Fi as energy very easily.
For this, they have developed a new type of antenna that captures the electromagnetic waves carried by Wi-Fi and converts them into direct current by using it as a radio frequency antenna.
This conversion requires a rectifier component that is inflexible, but the MIT researchers used the extremely thin and flexible material molybdenum disulfide, one of the world’s thinnest semiconductors.
According to the researchers, such a design helps create a fully flexible device that is fast enough to cover the radio frequency bands used in everyday electronic products, including Wi-Fi, Bluetooth, cellular LTE and others. .
So far, during experiments in this regard, scientists have been able to generate 40 microwatts of electricity from Wi-Fi signals, which is enough to light up a mobile display.
