Bangladeshi researcher Dr. SaidulAlam Chowdhury, a Research Fellow at the University of Auckland, New Zealand, is developing an advanced 3D wireless charging platform titled “Smart Power Box”, capable of charging multiple electronic devices simultaneously without requiring fixed placement.
He has received a competitive research grant of NZD 114,000 from the Warwick & Judy Smith Engineering Endowment Fund to conduct this project.
On Sunday Dr. Saidul shared details about the ongoing research. It has also been published on the official website of the University of Auckland.
At present, most wireless charging technologies operate in a 2D plane where devices must be placed accurately on a flat surface to receive power.
Dr. Saidul’s innovation aims to enable charging within a 3D space, where the device’s position, angle or orientation will no longer matter. Multiple devices can be charged at the same time.
The Smart Power Box incorporates an advanced resonant coil system, intelligent inverter control, temperature and frequency optimization, EMF-compliant safety design, and multi-device detection capable of identifying and powering devices regardless of their placement.
Explaining the motivation behind the project, he said that people often struggle with tangled charging cables, adapters and multiple chargers at home or workplaces.
“I wanted to create a platform that works much like Wi-Fi. you won’t need to place the device in a precise location. It will charge from any orientation.
This idea led to the Smart Power Box project,” he said. He stated that the project began with a small concept prototype.
Later a research team was formed at the University of Auckland laboratory to work on system modelling, coil design and performance testing.
The technology is gradually moving toward a usable product. Highlighting key challenges in 3D wireless power transfer, Dr. Saidul mentioned extending the effective charging distance, ensuring energy efficiency, reducing EMI/EMF interference, maintaining safety standards, and lowering production costs.
“Overcoming these challenges is our main research objective,” he added. We aim to make the technology more efficient and affordable. We also plan to collaborate with industrial partners to take it to the commercial stage.
My hope is that this New Zealand-developed technology will see real-world application in international markets, he said.
Dr. Md. Salahuddin Mina, Professor of the Department of Physics at Khulna University said, Dr. SaidulAlam Chowdhury’s innovation is a significant technological breakthrough.
I believe this technology will make people’s daily lives easier, safer, and more efficient in the future.
His research is of international standard and capable of producing practical solutions, which will be highly beneficial for our society.
