Scientists invent charger powered by human voice
Scientists have developed a new way to charge gadgets that uses sound energy. According to Interesting engineering, this method allows charging devices without using traditional batteries, just using sounds such as the human voice.
The technology is based on the use of piezoelectric materials that convert sound waves into electrical energy. When sound waves interact with these materials, they cause microscopic vibrations that generate an electric current. This current can be used to charge electronic devices.
“The technology has the potential to become an environmentally friendly and efficient way to charge gadgets, especially in situations where access to the power grid is limited or non-existent. It can be especially useful for portable devices such as smartphones, headphones, or medical devices,” the inventors said.
The technology is currently under development: scientists are working to improve its efficiency and practicality. They are also exploring the possibilities of integrating this system into various electronic devices.
