More than 43 million people worldwide are blind. In the past 30 years, that number has increased by roughly 50%. Most blind people are born with normal vision and lose their sight over time, due to ...

In this paper, a dual-frequency wireless power transfer method is proposed, capable of achieving controllable routing and providing power through magnetic coupling resonance to various positions on a ...

Magnetically coupled wireless power transfer (WPT) technology has been applied in stationary consumer electronics and holds great potential for charging traveling electric vehicles. The efficiency of ...

Based on a recent study at the University of Auckland, Wireless Power Transfer (WPT) technology, both dynamic wireless charging (DWC) and stationary wireless charging (SWC) will play a major role in ...

Accounting for radiation loss is the key to efficient wireless power transfer over long distances. A better way to wirelessly charge over long distances has been developed at Aalto University.

The efficiency of wireless charging systems is limited by power loss occurring due to frequency changes in the resonant circuits that enable power transfer. These necessary modulations reduce ...

What do e-bikes and laptops have in common? Both can be wirelessly charged by induction. E-bikes and laptops both use lithium-ion batteries for power, chosen for their light weight, high energy ...

ORNL’s Omer Onar, left, power electronics research lead, discusses the 270-kW wireless charging system’s lightweight polyphase electromagnetic coupling coil, pictured in foreground, with Lee Slezak, ...
