In today’s world, recycling and responsible energy consumption have gained significant importance as ways to preserve natural resources for future generations. One innovative option that has emerged is the use of Wi-Fi signals to generate energy.
Many ideas that seemed far-fetched just a couple of decades ago have now become integral to our everyday lives. Wind farms, solar energy, and electric cars are just a few examples of this shift.
There has been extensive research aimed at enhancing the energy efficiency of various eco-friendly initiatives in the pursuit of environmental conservation.
This focus on environmental advancements often doesn’t sit well with those who consider themselves the gatekeepers of truth.
Professional and critical journalism serves as a cornerstone of democracy. As a result, it can be unsettling for those who believe they hold the ultimate truth.
A key component of the systems mentioned earlier is batteries. There has been a concerted effort to improve their performance and lifespan to reduce technological waste. These batteries increasingly require advanced electronic chargers, such as smart chargers that monitor critical parameters to extend their longevity. However, all chargers need a power source, whether renewable or otherwise.
In 2022, a group of students and faculty members from UADE became interested in researching electromagnetic energy, particularly in the Wi-Fi range. Our goal was to explore how to capture this energy to power a battery charger by harvesting radio waves, which are commonly available in urban and semi-urban areas.
Throughout 2023, we dedicated ourselves to this research project. There were scant precedents on the topic, primarily limited to preliminary calculations. We faced numerous challenges, particularly in sourcing specific components that were hard to find. One motivating milestone was Sony’s experiment, which demonstrated the potential to power a circuit using absorbed surrounding electromagnetic energy.
By the end of 2023, we conducted tests on a prototype that successfully generated direct current (DC) electricity from an electromagnetic energy source. This project also has an ecological aspect since we are utilizing the surrounding electromagnetic radiation as our energy source. Our aim was to develop a prototype that didn’t draw power in the same way as traditional chargers.
While the initial tests produced a small amount of electricity, the prototype has shown the potential to generate enough energy to charge a battery or power a device within a reasonable timeframe. This is the challenge we are embarking on in 2024, and we are currently assembling the second stage of the prototype.
This line of research warrants attention, as the energy source we are utilizing not only reuses a resource available in most homes and workplaces but also holds growth potential that can be leveraged across various domestic, corporate, and industrial applications.
