2. Wireless power transfer - Wikipedia

   en.wikipedia.org/wiki/Wireless_power_transfer

   Generic block diagram of a wireless power system. Wireless power transfer (WPT; also wireless energy transmission or WET) 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 transmits ...

3. Resonant inductive coupling - Wikipedia

   en.wikipedia.org/wiki/Resonant_inductive_coupling

   Wireless electric energy transfer for experimentally powering electric automobiles and buses is a higher power application (>10 kW) of resonant inductive energy transfer. High power levels are required for rapid recharging and high energy transfer efficiency is required both for operational economy and to avoid negative environmental impact of ...

4. Inductive charging - Wikipedia

   en.wikipedia.org/wiki/Inductive_charging

   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 ...

5. Qi (standard) - Wikipedia

   en.wikipedia.org/wiki/Qi_(standard)

   Qi (pronounced / tʃ iː / CHEE; [1] from simplified Chinese: 气; traditional Chinese: 氣; pinyin: qì) is an interface standard for wireless power transfer using inductive charging. The standard allows compatible devices, such as smartphones , to charge their batteries when placed on a Qi charging pad, which can be effective over distances ...

6. Rectenna - Wikipedia

   en.wikipedia.org/wiki/Rectenna

   Rectenna. A rectenna (rectifying antenna) is a special type of receiving antenna that is used for converting electromagnetic energy into direct current (DC) electricity. They are used in wireless power transmission systems that transmit power by radio waves. A simple rectenna element consists of a dipole antenna with a diode connected across ...

7. WREL (technology) - Wikipedia

   en.wikipedia.org/wiki/WREL_(technology)

   WREL (an acronym for Wireless Resonant Energy Link) is a form of wireless resonant energy transfer technology developed by Intel . The technology relies on strongly coupled based on resonant inductive coupling caused by electromagnetic resonators, a principle similar to the way a trained singer can shatter a glass using his/her voice. [1]

8. Conductive charging - Wikipedia

   en.wikipedia.org/wiki/Conductive_charging

   A charging cradle with contacts that connect to the device being charged. Conductive power transfer uses electrical contacts to connect a power supply to a portable device in order to transfer energy. The technology is sometimes called "conductive wireless charging". [1] The need for a conductor-to-conductor connection between the power supply ...

9. eCoupled - Wikipedia

   en.wikipedia.org/wiki/ECoupled

   eCoupled. eCoupled is a proprietary near-field wireless energy transfer technology developed by Fulton Innovation, a division of Alticor. It provides wireless power transfer via inductive coupling between a primary transmission coil and a secondary receiving coil. A single primary coil can provide power to multiple secondary coils at the same time.
