Powermat, an Israeli startup company, has developed technology for providing wireless power to electronic devices. According to Powermat, its technology makes it for possible for electronic devices to be used without the need for socket-based or battery-based power.
Using principles of magnetic induction, Powermat's technology uses an ultra-thin mat embedded in or placed on a work surface or wall to transmits electrical power to portable electronic devices placed anywhere on the surface.
A ‘puck’ is placed on or next to the mat, and a handshake process synchronizes the mat with the puck. When this happens, only the coils next to the puck are activated. Electric power is generated in the puck to power the connected device. The mat provides power on demand, since power is only delivered to the connected device and not to any other items on the active surface.
Powermat claims that its technology offers a scalable solution for large work surfaces and areas that can be integrated in building construction and furniture design. The idea is similar to the technology being promoted by Cambridge (England) based Splashpower, a startup that has developed a wireless inductive electrical charging system for portable electronic equipment.
The Splashpower inductive charging system is based on a flat pad that plugs into the main electricity supply, called the SplashPad, and a special SplashModule fitted in a piece of equipment to supply direct current to charge an on-board battery. A SplashModule-enabled equipment item can be charged whenever it sits on the SplashPad. It delivers power wirelessly and can be used to charge multiple devices, including mobile phones, PDAs and personal music players.
