The transmission of electrical energy without the need of cables as a physical link is known as wireless power transfer. The same fields and waves that wireless communication devices use are also used by wireless power. For wireless power transfer, various radio-frequency (RF) methods are employed.
Remote places can also receive power using wireless power transmission. Currently, consumer electronics, which includes smartphones, laptops, and tablets, make up the majority of devices that utilise wireless power transmission.
Notably, the Healthcare, Defence, and Industrial Applications sectors are progressively implementing wireless power transfer technologies.
The Global Wireless Power Transfer Technology For Electronic Card Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
For electronic cards such as cards for fingerprint authentication, Murata Manufacturing has developed a wireless power transfer technique that receives more power from an NFC reader terminal. This technology is already being offered as a technical solution by Murata.
This technology helps shorten the time needed for fingerprint authentication and allows a fingerprint authentication card to be utilised away from NFC reader terminals even if the card is battery-less.
This technology makes it possible to create electronic cards with functions like display, sensing, connectivity, and others in addition to fingerprint authentication cards.
TDK has been spearheading the development of R&Ds required in creating wireless power transfer technologies, such as electromagnetic induction and magnetic resonance systems, from the very beginning. TDK is a participating business in both WPC and the AirFuel Alliance. It has produced goods to fulfil a variety of requirements, such as coils for wireless power transfer.
On its official website, MICROCHIP has introduced a 300W medium-power wireless charging solution. The transmitter and receiver, both of which are constructed with green PCB boards, make up the set of this MICROCHIP 300W wireless charging module.
Additionally, it has a larger cooling sheet on the front and has four filter capacitors and a rectifier inductor installed. The WP300RX01 and the chip work together to make the chip a wireless power receiver. The maximum power that can be transferred using the digital controller function is 300W.
