Abstract: The present disclosure relates to systems and methods for tunable electrodynamic wireless power receivers. In some examples, a wireless power receiver electromechanically converts energy from a magnetic field using an oscillating or continuously rotating magnet. A sensing device detects an operational parameter of the receiver, and a tuning device initiates a tuning action based on the operational parameter.

Abstract: The present disclosure relates to systems and methods for electrodynamic wireless power receivers. In some examples, a wireless power receiver electromechanically converts energy from a magnetic field. The wireless power receiver includes a planar suspension structure and at least one magnet. The planar suspension structure is tuned to cause oscillation of the at least one magnet at a resonance frequency based on a frequency of the time-varying magnetic field to generate electrical energy in the wireless power receiver.

Abstract: The present disclosure is directed towards wireless power transfer using one or more rotating magnets in a receiver. An exemplary embodiment provides for a system comprising a transmitter that generates a dynamic magnetic field and a receiver comprising a magnet and a coil. In operation, the magnet rotates in response to the dynamic magnetic field and induces a voltage across the coil.
