A group of scientists from the Massachusetts Institute of technology (MIT) have created a battery that receives energy from Wi-Fi. As a source of electricity the device uses the so-called Wi-Fi radiation. The battery receives power for connected devices out of thin air, writes about Politics.
On the official website of MIT says that the device is a variant of the antenna with built-in rectifier (diode). Energy can be obtained from a range to 10 GHz, i.e. from Wi-Fi, Bluetooth, and the radiation of base stations of cellular communication.
New development can be useful for medical applications (medical sensors) and also for mircochips or implants. Today in medicine used lithium-ion batteries, which pose a danger to health.
While it is unknown when “eternal” battery will be released to the market. At the moment, the scientists plan to create a larger antenna, and also to increase effectiveness of the existing prototypes.
