Abstract
Methods, apparatuses, and systems for wireless power transfer (WPT) in ball-and-socket type structures are provided. A ball and ball-socket structure can include conductive windings and conductive plates having a variety of shapes to optimize WPT over different angles as the ball moves or rotates within the ball-socket. One or both of capacitive coupling and inductive coupling can be incorporated.
