Wireless Power Transfer (WPT) is a technology that allows electrical energy to be transmitted from a power source to an electrical device without the need for physical connectors or wires. This process typically uses electromagnetic fields to transfer energy over short distances. Common applications include charging devices like smartphones and electric toothbrushes, where convenience and ease of use are essential. There are several methods of WPT, including inductive coupling, which uses coils to create magnetic fields, and resonant inductive coupling, which allows for greater distances and efficiency. As technology advances, WPT is being explored for use in electric vehicles and other applications, potentially revolutionizing how we power our devices.
