Harvesting energy from radio waves is a growing field of research that has the potential to revolutionize the way we power our devices. The technology works by capturing the energy from radio waves that are present in the air and converting it into usable electrical power. This type of energy harvesting is known as radio frequency (RF) energy harvesting.
Advantages
One of the main advantages of RF energy harvesting is that it can be used to power devices in remote or hard-to-reach areas, such as sensors in remote forests or oil rigs in the ocean. Additionally, RF energy harvesting can be used to power small devices, such as wearables or IoT sensors, that require low levels of power.
Ways of Harvesting
There are several different ways to harvest energy from radio waves. One of the most common methods is through the use of antennas, which can capture the energy from radio waves and convert it into electrical power. Another method is through the use of rectifiers, which can convert the AC energy from radio waves into DC energy that can be used to power devices.
Another method is using a technology called “Metamaterials” which are artificially created materials that can be designed to interact with electromagnetic waves in ways that natural materials can’t. This can be used to create more efficient RF energy harvesting.
Researchers are also exploring ways to use RF energy harvesting to power larger devices, such as electric vehicles or even buildings. However, more research is needed before this technology can be widely adopted on a large scale.
Overall, RF energy harvesting has the potential to be a game-changer in the world of energy. It is a clean, renewable source of power that can be used to power devices in remote or hard-to-reach areas, and it has the potential to be used to power larger devices in the future.
I learn that Filipino inventors are also developing something like this technology and it would be such a great negosyo idea.
