The manner in which we charge our phones has mostly stayed the same.
But as one team of scientists found nearly 12 years ago, there may be other options available to deliver the power needed to keep our phones at 100%. Innovation in the technology sector has been a major path to increasing the efficiency of the most important devices in our lives.
How could we possibly charge our phones using sound waves?
How a simple communication device changed the world forever
Our phones have become the key to opening a treasure trove of possibilities.
The economic leapfrogging that took place in Africa saw the M-Pesa service revolutionize personal finance options. The service was the first on the continent to offer millions of people access to their bank accounts right on their phones, something we all take for granted now.
And the mobile phone market is only growing with every passing year.
In 2024, data revealed that there are more active mobile phone connections in the world than there are people. And the access to emergency medical response has also been boosted by our phones, as 40% of users admit to contacting EMS during emergencies directly on their phones.
The energy needed for everyday life is limited, so what do we do now
The only option available is to innovate the energy industry to create more power.
Oil has taken us as a society this far, but even it has a dark and harmful side that has been emerging more and more in recent times. Oil refineries are littered with potential dangers around every corner.
Creating new and revolutionary methods to generate power has become all too real in recent times.
Every single thing you can think of in your home needs power. From your kettle that boils your water for that delicious morning cup of Joe, to the more recent electric vehicles that now dominate the highways of the nation, energy is a hot commodity.
But energy is expensive, regardless of whether it comes from oil or the renewable energy industry.
As we all face the monthly sky-high electric bills, which have become even worse due to the cold weather that blanketed certain parts of the nation, an old development from Queen Mary University of London may have had the answers. At least the answers to powering our phones, that is.
We could all use a little good vibrations in our lives, and phones, too
A team from Queen Mary University of London created a prototype smartphone nearly 12 years ago that could be charged using nothing but the energy of sound.
The device used “nanogenerators” that were made from zinc oxide nanowires that converted vibrations from everyday noises like traffic, music, or even our own voices into electricity.
The technology was seen as a major step forward in reducing the everyday energy needed to power our cellphones.
Despite the promise, the project never materialized to reach its full potential
However, the technology was never really taken seriously by the phone manufacturers of the world and never became a commercially viable option. The reasoning for this project ending badly was never fully understood, as the tech could have saved vast amounts of energy.
The trend of the energy sector forgetting about potential innovations is not a new one, as one scientist found out to his detriment in 2007.
Phone manufacturers stated that the power generated by this innovative tech was not able to scale up to acceptable levels for large-scale use by millions of smartphone users across the world.
We need to reexamine old tech from twenty years ago, as the likelihood that we missed something that could reshape the energy world is very high indeed.
