Helsink, Finland: Scientists from University of Helsinki and University of Oulu have achieved a significant breakthrough in wireless power transmission technology. The research team successfully demonstrated a novel method of delivering electricity without the use of physical cables, plugs, or connectors.

The technology works by transmitting electrical power through an invisible channel referred to as an “acoustic wire.” This channel is created using a combination of ultrasonic sound waves, laser beams, and specific radio frequencies to guide the electrical current to a designated target area.

During experimental trials, the system was able to supply low-voltage electricity sufficient to operate electronic and smart devices. The successful transmission confirms the feasibility of delivering power wirelessly with precision and stability.

However, researchers emphasized that further testing and development are required before the technology can be scaled to transmit higher levels of electricity for broader industrial or commercial applications.
