  • TUNABLE ELECTRODYNAMIC WIRELESS POWER RECEIVERS
    Publication number: 20250175033
    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 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.

  • Tunable electrodynamic wireless power receivers
    Patent number: 12272964
    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.

  • Electrodynamic wireless power receiver
    Patent number: 11368049
    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.

  • Wireless power transfer using one or more rotating magnets in a receiver
    Patent number: 10218221
    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.
