wireless transmission of energy

Wireless transmission of energy involves transferring electrical power from a source to devices without physical cables, using electromagnetic fields. Typically, this is done through methods like resonant inductive coupling or electromagnetic waves, where energy is converted into radio frequency or magnetic fields that travel through the air. When these fields reach a compatible receiver, they induce electrical current that can power or charge devices. This technology enables convenient, cable-free charging for electronics and has potential for applications like powering remote sensors or medical implants, reducing the need for physical connections while maintaining efficient energy transfer.
