The number of devices used by the average consumer that require charging continually increases. A household having multiple devices understands the hassle of connecting devices with charging cables. However, a number of companies are finding ways to make wireless charging more convenient and more readily accessible.
In the 19th century, Nikola Tesla developed the coil that bore his name in an attempt to transfer power wirelessly. Although his innovation failed, the theory intrigued many. By the 21st century, technological advances arose that made the possibility a reality. Today, there are a number of existing and start-up companies offering hope for the future in the field of wireless charging .
The company remains busy designing and constructing high-capacity charging systems having capabilities ranging from 1,000 to 20,000 watts. The systems would be capable of charging everything from industrial equipment to electric hybrid vehicles. The technology relies on magneto-dynamic coupling. The transmitters and receivers contain a pair of spinning magnets, which are separated by air. When the magnets in the transmitter spin, the magnets in the receiver follow suit. The action enables a transfer of power without producing a vast quantity of heat.
The company’s WattUp wireless system enables users to recharge a variety of electronic items as long as they are located within proximity of the charging platform. The device features a transmitter containing a series of antennas that transmit RF signals to a receiver. WattUp uses Bluetooth to locate smartphones, tablets or other devices that use the Energous app. When the transmitter finds the devices, RF signals travel to the individual devices, which then convert the energy to direct current.
The system developed by the company makes use of infrared light and is capable of power everything from smartphones and fire alarms to electronic locks. The transmitter emits a small beam of infrared light. Receivers within the smart items convert the beam into electricity.
The startup company uses ultrasound to transmit power. A speaker-like transmitter releases high-frequency sound waves that are out of the human hearing range. An array of antenna channels the sound to a receiver. Compatible devices convert the sound waves into the current for charging. Once the system detects that the devices are fully charged, the transmission of sound waves stops.
