Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...

Wireless Power Transfer relies on magnetic induction between a planar receiver and transmitter coils. When the receiver coil is positioned over the transmitter coil, magnetic coupling occurs when ...

In order to ensure smooth wireless power transfer, the Wireless Power Consortium established WPC 1.1 Standard (July 2012) to facilitate cross compatibility of compliant transmitters and receivers. The ...

A great improvement has been demonstrated in the distance that electric power can travel wirelessly. Researchers developed the 'Dipole Coil Resonant System' for an extended range of inductive power ...

Recent innovations have enabled the creation of robust and reliable wireless power systems that can be tailored for use in a wide variety of industrial and consumer settings. There are two key design ...

The Wireless Power principle is more than 120 years old. John Perzow, VP of Market Development for the Wireless Power Consortium (WPC), tells us in his Wireless Power blog on Planet Analog : This ...

This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...

It’s wasn’t so long ago that RC transmitters, at least ones worth owning, were expensive pieces of gear. Even more recently than that, the idea of an RC transmitter running an open source firmware ...

A wireless charger that's compatible with different consumer electronics from different brands is one step closer to becoming a reality thanks to research by electrical engineers at the University of ...
