Scientists in Finland have achieved a major technological breakthrough by successfully transmitting electricity through the air without the use of wires.

The researchers used a combination of ultrasonic sound waves, lasers, and radio frequencies in what they describe as a magneto-inductive technology to move electrical energy across open space. This method allows power to be delivered remotely without physical cables or direct contact between the power source and the receiving device.

According to the research team, the system works by creating controlled electromagnetic fields that guide energy through the air and convert it back into usable electricity at the receiving end. The added use of ultrasonic waves and lasers helps stabilize and direct the energy flow more precisely.

Experts say this innovation could revolutionize wireless charging, medical implants, robotics, and remote power delivery in hard-to-reach environments. It could also reduce dependence on traditional power cables in homes, factories, and future smart cities.

While the technology is still in its early stages, scientists believe further development could make safe, long-range wireless power transmission a practical reality in the near future.
