Wireless power transfer is a breakthrough technology that allows devices to connect to each other and to transfer power between them. Its advantages include safety and convenience. It also saves on labor costs and increases reliability. The technology can be used for many different applications, including cars, public transportation, and toothbrushes. Wireless power transfer is a promising technology that could revolutionize how we live.

Wireless power transfer works by transferring energy between two devices through the use of electromagnetic fields. In a wireless power transfer system, these waves are sent by a transmitter to a receiver through a high-frequency power supply. These waves have different effects on the human body, and they behave differently on different materials.

Wireless power transfer systems are rapidly gaining popularity in many different applications. This technology is already being commercialized in mobile phone chargers, stationary charging electric vehicles, and dynamic charging of EVs. It is anticipated that wireless power transfer will become ubiquitous in our society over the next few decades. This chapter explores wireless power transfer in detail and describes some of the latest advancements in the industry.

Wireless power transfer uses the same waves and fields as radio waves to transmit electrical energy without wires. Wireless power transfer is currently used in cell phones, WiFi, and radio broadcasting. Depending on the device and the location, the amount of energy sent may not reach the receiver. However, in wireless power transfer, the amount of power that reaches the receiver is only a fraction of the total power transmitted. This makes efficiency an important factor.

The earliest wireless power transfer technology was developed by Nikola Tesla. This wireless power transfer technology is used for battery charging of mobile devices, batteries in electric vehicles, and industrial applications. Modern wireless power transmission techniques include electromagnetic induction, magnetic resonant induction, and microwave power transmission. These technologies are ideal for long-range wireless power transfer.

Wireless power transfer can be effective and inexpensive. A variety of charging stands and pads use this method. This method also supports a range of power levels. However, it is limited by its limited magnetic coupling. It also requires an amplifier unit. If the devices are close enough, the wireless power transfer system can be highly efficient.

Wireless power transfer systems must meet certain basic restrictions to be safe for the human body. The radio-wave system must have high-frequency waves and narrow beams in order to transfer power effectively. Early steps were made in this field during the Second World War with the development of microwaves, magnetrons, and parabolic antennae.
