Safety, energy and charging efficiency drive choice of close-range magnetic induction technology in the standard for wireless power transfer
"There's something futuristic about wireless power that has grabbed people's attention at the Consumer Electronics Show this week, and 2009 could be a big year for the technology judging from what's on show here ... One issue for all the vendors will be agreeing to a standard that lets their products interoperate." -
Close-range magnetic induction technology differentiates itself from other wireless power technologies by transmitting power within a near field between the devices to be charged and the power source. This range can be less than one centimeter and allows the transmitter to focus energy on the receiver safely with high efficiency.
The first products targeted for the standard and a universal wireless charging solution will be 4-5 watt portable electronic rechargeable devices. This includes smart phones, mobile phones, portable music and video players, batteries and battery charging packs, computer and game peripherals, remote controls, Bluetooth(R) headsets, digital still cameras, camcorders and shavers.
Advantages of close-range magnetic induction technology
Close-range inductive coupling technology is based on the principle of magnetic induction, a technology in use in a variety of applications for over 100 years, because it is simple, efficient and safe.
The technology makes rapid battery charging possible and charges in the same time as current wired chargers. It is safe and will not interfere with data or devices nearby. Close-range magnetic induction does not require contact between the device to be charged and the power source. Loss of energy and impact on the environment are also minimized. It performs reliably in demanding environments where there may be water and dirt.
