New Metamaterial Wireless Charging Efficiency

According to the mass science website recently reported that the research team led by Zhang Xiang, Duke University, said they are using new metamaterials, trying to develop a new type of "metamaterial lens" to better control the light passing through the lens, thereby enhancing the pmission of wireless power.

Metamaterials

While pmitting wireless power, the interference caused by microwave or laser can be avoided.

The lens made of this metamaterial is placed between a power supply and a device ready to be charged to fill the gap between the power pmission device and the receiving device.

Previously developed metamaterial lenses can only pmit weak electrical power in a small range, such as radio frequency identification (FRID) equipment or near field communication.

If this method is used to charge a cell phone, a high-power microwave oven or even a laser device, more power will be pmitted, but the existing technology may cause these devices to catch fire.

The metamaterials developed by Duke University include an array of thin conduction loops, which are made of conductive copper glass material and may look like a set of movable shutters.

The new metamaterials can make wireless power pmission simpler and safer. The lenses made by them will focus the electric energy and make the power more stable and more concentrated through the open space without diverging.
