Miniaturized Highly Efficient Wireless Power Transfer (WPT) System


Florida International University (FIU) is seeking a business partner to develop and commercialize a Miniaturized WPT system that used multiple layers of resonators and/or tunable capacitors.

WPT often uses inductive power delivery, which is the use of non-radiating magnetic fields generated by a transmitter coil to induce a current in a receiver coil. The coils are close to each other for the desired strong inductive coupling. Strongly coupled magnetic resonators systems have shown good efficiency and range, but they require a certain distance between the source and the resonators, and therefore occupy a significant volume.

To address this problem, FIU inventors have designed advantageous systems and methods for WPT via multiple-resonator conformal strongly coupled magnetic resonance. Instead of using a single loop as a resonator, multiple resonators (e.g., using multiple loops) were used in a multi-layer. It was shown that the system was able to operate at a lower operating frequency, extended WPT range and higher WPT efficiency.


Charging of: mobile devices, implantable devices or sensors, embedded sensors for structural health monitoring of concrete structures and bridges, wearable devices and healthcare applications

  • Miniaturizes size of standard WPT systems
  • Extends the range of standard WPT systems (e.g. 20% increase)
  • Lower operating frequency (e.g., 30% decrease)
  • Higher WPT efficiency compared to single-resonator systems of the same size
