Everyone loves wireless power these days, almost vindicating [Nikola Tesla’s] push for wireless power. One reason why transmitting electricity this way is a terrible idea is the massive losses ...

SAN FRANCISCO, Calif. — A researcher from Keio University in Japan showed a way to put an entire solid-state disk in the footprint of a single chip in an evening talk at the International Solid State ...

That’s an interesting question, and the answer is beyond my knowledge of RF engineering, so I reached out to Neeraj Sood, a researcher at the University of Toronto and a member of McMaster ...

In the 1890s, Nikola Tesla captured the imagination of the world with his invention of the Tesla coil, a device that could transmit electricity through the air, no wires required. More than 100 years ...

Wireless charging system described by using the method of inductive coupling. In this paper, oscillation circuit converts DC energy to AC energy (transmitter coil) to transmit magnetic field by ...

Solution for Difficult Retrofit Bryan Nicholas CML, of San Diego-based Door Systems Inc. needed to power the electric strike on a removable mullion. Years of real-world experience convinced the ...

In this paper, the authors present the concept of transmitting power without using wires i.e. transmitting power as magnetic waves from one place to another is in order to reduce the transmission and ...

Compared to wired, or direct contact, charging methods, inductive chargers are generally less efficient and require larger internal components to operate. In addition, the sensitive inductive coils ...

In technical terms, inductive coupling is the transfer of energy from one circuit to another by virtue of the mutual inductance between the circuits. In an RFID system that uses inductive coupling, ...
