Researchers have shown that electrical energy can be transmitted through open air using a combination of ultrasonic sound waves, laser systems, and radio-frequency technologies. In Finland, scientists at the University of Helsinki and the University of Oulu are exploring multiple wireless power methods, positioning the country at the forefront of next-generation energy research. One experimental approach uses high-intensity ultrasonic waves to temporarily structure the air, creating a guided pathway for electrical discharges. Often referred to as an “acoustic channel,” this technique relies on sound rather than physical cables to direct electricity. Although still in the laboratory phase, the technology could eventually enable contact-free electrical connections, allowing devices to operate without plugs, sockets, or conventional wiring. Finnish innovation also extends beyond sound-based systems. Private-sector companies are developing laser-powered energy transfer, where focused light delivers electricity to remote receivers. This method is especially valuable in environments requiring strong electrical isolation, such as nuclear facilities or high-voltage sites. Meanwhile, researchers are advancing radio-frequency energy harvesting, capturing ambient electromagnetic signals to power low-energy devices. This approach could significantly reduce dependence on disposable batteries in sensors and Internet-of-Things applications. Together, these breakthroughs point toward a future where electricity can be delivered more safely, efficiently, and flexibly transforming how energy is distributed across industrial and technological systems.
