Current methods for charging electronic devices via wireless technology only work if the overall system parameters are set up to match a specific transfer distance. As a result, these methods are limited to stationary power ...
(Phys.org)—Currently, commercial wireless power transfer is limited mainly to charging pads for phones: instead of plugging your phone directly into the wall, simply place it on top of a wireless charging pad. In the future, ...
(Phys.org)—Over the past decade, research on wireless power transfer has led to the development of several commercial applications, such as wireless charging of mobile devices and electric toothbrushes, as well as wireless ...
(PhysOrg.com) -- A team of MIT physicists has developed a system that can wirelessly transfer power to multiple electronic devices simultaneously with high efficiency. The system takes advantage of electromagnetic resonance ...
Researchers working at the National Institute of Standards and Technology (NIST) have developed a "piezo-optomechanical circuit" that converts signals among optical, acoustic and radio waves. A system based on this design ...

During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).

(Phys.org)—Researchers at the University of Illinois in Chicago have developed a special set of body modules that provide wearers with extra-sensory perception as to who or what is nearby. The design could help the blind ...
(Phys.org)—It's relatively simple to build a device capable of detecting wireless signals if you don't mind making one that consumes lots of power. It's not so easy to design energy-efficient devices that function as well ...
