Wires – the one stretch of material that makes the line between true mobility and the quest for plug-points. The search for wireless power solutions has been on for quite a while. Wikipedia tells us that the principles underlying the basis wireless energy transfer date back to 1825.
The advent of computing systems as our constant companions, the miniaturization of electronics and the innovation on the power efficiency front have made it more and more probable to enjoy the true virtues of mobile computing. The last mile on this front is a total wireless power solution and Technology Review mentions on how the technology of resonant coupling may perhaps present the solution.
There are currently solutions out in the market that do make wireless transmission quasi-wire-free. For example, there is the WildCharger pad makes charging devices as simple as putting them on a tray.
The following years do hold a lot a promise on this front and combined with equipped smart electronics, they could usher in an era where charging would no longer requires human intervention.
