Dr Katie Hall is developing ways to transfer power without wires . This distance -- Hall explains -- is linked to the size of the coil , and WiTricity wants to perfect the same long-distance transfers to today 's small-scale devices . The idea of using electricity as a form of energy has been around for centuries, but it was only in the last few decades that we started seeing how useful this could be - and now it's The technology could lead to new and revolutionary medical devices .
