Wireless charging is the process of recharging batteries of electrical devices without using physically connected electric cables. The communication between transmitter (power source) and receiver (device) is generally by microwave or electromagnetic induction. With the emergence of wireless chargeable devices, the need to carry multiple chargers for various devices will become obsolete. Chargeable devices such as mobile phones, and tablets need to be handier. Wireless charging technologies are revolutionizing the current electronic devices market to meet the demand for more efficient, standardized, safe and portable power recharging options.
Wireless charging is more applicable to charge smartphones, tablets and other small handheld devices and wearable technologies. The obvious benefits associated with the use of wireless charging includes efficiency of handling, protection from electric shocks, safe charging option for devices that need to be waterproof, no need for maintenance of charging cables and associated sockets. On the other hand, wireless charging technology is comparatively less efficient, slow, and expensive. Most devices also radiate heat during the charging process.
The global wireless charging market recently reported its development, due to continuous updation in phones. The demand for sealed devices, increasing demand for power for devices and inconvenience associated with carrying multiple chargers are the key drivers behind growth of wireless charging technologies. The key restrains behind wireless charging are lack of standardization and expensive infrastructure to pursue technological developments. Many advanced products are still in experimental phase but on the other hand these products have a bright future opportunity.
Wireless charging can be broadly categorized into two types depending upon proximity of distance between transmitter and...
