WPT stands for wireless power transfer. It typically relies on inductive coupling between two coils to push energy across a small air gap, charging devices like smartphones, electric toothbrushes, or medical implants. Advanced forms use resonant inductive coupling or RF energy harvesting to increase the transmission distance.
