Coil design, receiving coil, wireless power transmission, inductive link, and in vivo robotic capsules.


This paper suggests an arrangement method of coils to provide hundreds of mW power via inductive link to in vivo robotic capsules, whose orientation are practically undetermined. We propose that the orthogonal coils in 3 dimensions could provide power amounting from sixty to one hundred percent of the maximum possible power of one receiving coil regardless of the orientations of the machines.
