Abstract: This paper presents a wireless power transfer (WPT) system using a bowl-shaped transmitting (Tx) coil and its application for charging small electronic devices such as hearing aids and ...

The system uses a long-track transmitting coil, rectangular receiving coil, and LCC-S resonance compensation topology. First, the charging power and energy transmission efficiency are calculated.

This year's upcoming iPhone 8 product line is widely expected to be Apple's first generation of smartphones to feature wireless charging capabilities, finally freeing up iOS users from their ...

The research demonstrates groundbreaking improvements in wireless charging efficiency through innovative coil designs. By integrating ferrite boxes into circular coils, the team achieved a remarkable ...

to get to the metallic charging coil underneath. Some of that energy dissipates in the process, where it turns into heat. Even so, you can use your phone while charging it wirelessly. However ...
