Most state-of-the-art methods of wireless energy delivery are inherently limited to static devices. An approach based on fundamental physics could overcome this limitation, opening up a wealth of ...

Using a wireless charger with your smartphone can use as much as 40 percent more energy than doing so with a traditional ...

It's way more convenient, but way less efficient.

Wired charging can be better for the planet and your time.

Converting the radio transmissions in the air into power. All wireless signals comprise energy and data, the latter derived by the way the radio waves are modulated. Wireless energy harvesting (WEH) ...

DARPA has tapped Raytheon to design and develop a wireless, airborne relay system to "deliver energy into contested environments," as part of its Energy Web Dominance program, in which DARPA wants to ...

A team from Georgia Tech has just announced a world-first: a 3D-printed rectifying antenna the size of a playing card that can harvest electromagnetic energy from 5G signals and use it to power ...

Will electric vehicles someday be charged as they roll down the highway? Dynamic wireless charging—charging a vehicle as it travels down a specially-equipped road—is still in the research stage, but ...

Radio-frequency (RF) wave rectifier circuits play an invaluable role in extracting the appropriate DC voltage and current in wireless energy applications, such as mobile power supplies and ...
