Inductive charging. The primary coil in the charger induces a current in the secondary coil in the device being charged. Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in ...
The technology is sometimes called "conductive wireless charging". The need for a conductor-to-conductor connection between the power supply and the device is the main difference from inductive charging and other forms of wireless charging. The conductive power supply, often a charging base or pad, detects when a compatible receiver or pickup ...
Near-field communication ( NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 centimetres (1.6 in) or less. [ 1] NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. [ 2]
That’s why you need a wireless charger — a handy device onto which you can put your phone to charge (or indeed, any device) without the hassles of cables and wires everywh The best wireless ...
Wireless power transfer ( WPT ), wireless power transmission, wireless energy transmission ( WET ), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that ...
Resonant inductive coupling or magnetic phase synchronous coupling[ 4][ 5] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. [ 5] A resonant transformer of this type is often used in analog circuitry as a bandpass filter.
In a few years' time, fumbling around with messy cords and plugging your device into the wall charger will seem archaic. Honestly, it might even seem strange now, at least in the eyes of people ...
Wi-Charge was founded in 2012 by Victor Vaisleib, Ori Mor and Ortal Alpert. The company is developing a unique far-field wireless power technology based on infrared laser beams. In 2015, Wi-Charge demonstrated its first prototype capable of charging small electronic devices. [1] In 2017, the company claimed to obtain compliance with ...
