Wireless Charging tagged posts

A better way to wirelessly charge over long distances has been developed at Aalto University. Engineers have optimized the way antennas transmitting and receiving power interact with each other, making use of the phenomenon of “radiation suppression.” The result is a better theoretical understanding of wireless power transfer compared to the conventional inductive approach, a significant advancement in the field.

Charging over short distances, such as through induction pads, uses magnetic near fields to transfer power with high efficiency, but at longer distances the efficiency dramatically drops...

Devices can be charged regardless of their position or orientation and even on the go. A new power transfer technology makes it possible to conveniently charge devices without using any wires or plugs. Warehouse robots, kitchen appliances, and even phones or laptops can receive power anywhere over the charging area, and because the power transfer continues even while the device is in motion, this technology could one day power electric vehicles while they’re on the go.

The basics of wireless power transfer have been in place for some time, but existing systems are not able to charge devices placed anywhere within a large area...
