Just think a world where mobile phones, laptops, and other electronics are power without batteries. Studies from MIT computer science information and elsewhere have taken a step in that direction, with the first fully flexible device. That will change energy from signals of Wi-Fi into electricity that can power electronics. Tools that change AC into DC electricity are known as “rectennas.”
The analysts display a new kind of rectenna, described in a study appearing in Nature today. That applies a flexible radio-frequency antenna that captures electromagnetic waves that include those carrying Wi-Fi as AC waveforms. Then connected the antenna to a novel tool made out of two- dimensional semiconductor just a few atoms thick. Now the signal of the AC travels into the semiconductor. That change into a DC voltage that can use to power electronic circuits or recharge the batteries.
No Batteries for Mobile Phones
Further, the battery-free tools calmly catch and change everywhere the Wi-Fi signals into useful DC power. Furthermore, the tools are flexible and can be assembled in a roll-to-roll process to cover very large areas. For the proposed rectenna will give a big promise that includes powering flexible and wearable electronics, medical devices. As well as, sensors for the “internet of things.” With all of this innovation from a basic electronics course that we learn in the school. To a high technology now that discovering by the researchers.
Technology keeps on advancing and the demands are getting higher. But there is some weak reaction from other people that have no knowledge of the technology.
Most of these people are in the poverty line of our society. That has no ability to buy the latest mobile phone. These discoveries will not stop as long as there is a thing to discover. We are thankful to our scientist and researchers. That they keep on enhancing our surroundings with these changes in our technology.
