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 ...

Ultrasound-based wireless power transfer is becoming a more attractive option to power implanted biomedical devices because it could overcome many of the limitations and challenges facing other ...

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.

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 ...

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 ...
