Data has already gone wireless. Power is next. Imagine your telephone or tablet charging automatically when you toss it on the coffee table, and floor lamps that do not need trailing wires because they pick up their power from the carpet.
These are elements of the future envisioned by WiTricity, which licenses the use of a breakthrough technology developed at MIT. The technology, called highly resonant wireless power transfer, uses oscillating magnetic fields to induce currents in coils – but, unlike traditional induction, is able to transfer power efficiently over much larger distances and varying orientations. As it uses magnetic fields, which interact only weakly with biological organisms, it is not seen as posing health risks.
So you could, for example, use a laptop without a wire because it is drawing power from a wireless power source embedded in your ceiling, and charge your electric vehicle without plugging in because the power comes from a wireless source on the floor in the garage. Someday, sources in roads may even charge electric cars as they drive.
The technology also promises an end to the need for wires, and the consequent risk of infection, in implanted medical devices such as heart pumps. Built into rechargeable AA batteries, the technology provides portable power which is cheaper, more efficient and more environmentally friendly than today’s disposables.
WiTricity is working with manufacturers to license and embed its technology in a variety of devices, which will be available in the coming years.
