Wireless power transfer

Wireless power transfer is a technology that allows electricity to be transmitted through the air without the need for physical wires. This is achieved by using electromagnetic fields, where energy is generated and then transferred to a device, like a smartphone or electric vehicle, that captures and uses this energy. Common applications include wireless charging pads and some electric toothbrushes. This method simplifies the process of powering devices, reduces clutter from cords, and opens possibilities for innovative applications in everyday life and industrial settings.
